Setting up a used car dealership in Spain is an accessible business, but not a simple one. It does not require a million-euro investment to get started, but it does mean knowing the legal procedures, the sector’s tax rules and how used vehicle buying and selling transactions work.
Many dealers who have now been in the sector for years started with a small car park, 5 or 6 cars in stock and a lot of manual work. Some still run it that way. Others have professionalised their processes and grown. The difference almost always lies in how well they prepare the first few months: choosing the right legal structure, keeping the paperwork in order and setting up a management system that lets them scale without drowning in documents.
This article covers everything you need to know to open a second-hand car dealership, from choosing between self-employed and a limited company to how to get your first cars to sell.
Self-employed or limited company? How to choose the legal form
The first decision you need to make is whether you operate as self-employed (a sole trader) or as a company (usually a private limited company, S.L.).
Self-employed is the simplest option to get started. Registration is quick, administration costs are lower and you can benefit from the self-employed flat rate during the first year. The downside is that you are personally liable for the business’s debts with your own assets. If things go badly, your personal belongings are at risk.
Private Limited Company (S.L.) requires a minimum share capital of 1 euro (since the 2022 reform, although the usual recommended threshold is 3,000 euros), a notarial deed and registration with the Companies Registry. The main advantage is limited liability: you are only liable up to the capital contributed to the company. In addition, from a tax point of view it can be more advantageous once you reach certain turnover levels (roughly, from 40,000-50,000 euros in annual profit, the flat rate of Corporation Tax is usually more favourable than the self-employed person’s progressive Personal Income Tax).
The practical recommendation: if you are starting on your own and with little stock (fewer than 10 cars), starting as self-employed is the quickest route. If you are starting with a partner, significant investment or a large stock, an S.L. is worth it from day one.
Mandatory procedures and licences
Once you have decided on the legal form, these are the administrative steps you need to complete:
Register with the Tax Office. Register in the business census using form 036 or 037. You need to choose the relevant economic activity code for vehicle buying and selling (IAE code 615.1: "Wholesale of vehicles"). If you are also going to operate under the Special Scheme for Second-Hand Goods (REBU), which is the usual case, you must notify this at the same time.
Register with Social Security. Register with the RETA if you are self-employed, or register the company and the directors if it is an S.L.
Town Hall opening licence. You need an activity licence for the premises where you are going to operate. The type of licence and the requirements vary depending on the municipality and depend on the size of the premises, the location and whether you carry out complementary activities (workshop, car wash). This procedure can take between 2 weeks and 2 months depending on the town hall.
Register as a professional operator with the DGT. To transfer vehicles as a professional, you need to register as a DGT collaborator (vehicle administration agent). This requires a valid digital certificate, registration in the electronic notification system and compliance with data protection regulations. If you want to see the full registration process as a vehicle trader, we explain it step by step in our guide to registering as a vehicle trader.
Public liability insurance and stock insurance. Public liability insurance is mandatory if you open premises to the public. Stock insurance (which covers the cars you have on display against theft, fire or damage) is not legally mandatory in all cases, but it is highly recommended. An incident involving a stock of 15 cars could mean a loss of more than 100,000 euros.
The premises: what you need and what to look for
The space where you display and sell the cars builds trust or destroys it. You do not need a brand dealership with glass walls, but you do need a functional and presentable premises.
Minimum requirements: display area with capacity for at least 5-8 vehicles (outdoors or indoors), an office with internet connection for administrative management and customer service, toilets, and adapted access for people with reduced mobility if the premises exceeds a certain surface area (check local regulations).
Location. Ideally, a site with visibility from the road and easy access. Commercial estates or routes into medium-sized towns usually work well. A premises on a residential street without vehicle traffic may seem cheaper, but the lack of visibility translates into fewer walk-in visits.
Cost. In medium-sized towns, a premises or plot with space for 10-15 cars can cost between 500 and 1,500 euros a month in rent, depending on the area. In large cities (Madrid, Barcelona, Valencia), prices rise considerably.
Alternative: no fixed premises model. Some dealers operate from a car park or from their own plot, without a traditional commercial premises. This is legal if you comply with the activity licence and local regulations, but it limits the professional image and the ability to attract walk-in customers.
How much money you need to start
There is no single figure, but there is a realistic range. To set up a dealership with a minimum level of professionalism, you need to factor in:
Initial stock: between 5 and 10 cars to get started. If you work with mid-range vehicles (purchase price between 5,000 and 10,000 euros), this means between 25,000 and 100,000 euros. This is the largest item and the one with the most variability.
Premises (first month + deposit): between 1,000 and 4,000 euros.
Legal procedures and incorporation: between 500 and 2,000 euros (notary, registry, agency fees, opening licence).
Tools and equipment: computer, office furniture, signage, cleaning materials for the cars. Between 1,000 and 3,000 euros.
Management software, portals and website: between 100 and 400 euros a month, depending on the tools you use.
Insurance: between 1,000 and 3,000 euros a year, depending on cover and stock volume.
Working capital: it is advisable to have at least 3 months of fixed costs covered without relying on sales. Between 3,000 and 10,000 euros.
In total, a realistic start-up sits between 30,000 and 60,000 euros to begin with 5-8 cars and functional premises. If you want to go deeper into how to structure a business plan for your dealership, we recommend our article on how to prepare a business plan for a dealership.
How to get your first stock
The profitability of your dealership starts with buying, not selling. Choosing the first cars well is what makes the difference between starting with margin or starting by losing money.
Buy from private sellers. This is the channel with the greatest margin potential because there are no intermediaries. You can find opportunities on Wallapop, Milanuncios, Facebook Marketplace or by attracting sellers directly with a "we buy your car" page on your website. It requires more negotiation and more time for verification (mechanical condition, paperwork, outstanding finance), but it is the most profitable source in the long term.
Professional auctions. Platforms such as BCA, Autorola or Auto1 allow access to fleet cars, returned lease vehicles and finance returns. They offer volume and traceability, but the margin per unit is usually lower because you are competing with other professionals. They are a good option to complement stock.
Network of other dealerships. Buying from other dealers or swapping vehicles is common practice in the sector. You can get cars that do not move for another dealership but suit your customer profile.
Importing. Buying in Germany, France or the Netherlands can be profitable in specific models (premium, automatic, electric), but it involves type approval, import MOT, logistics and specific paperwork. It is not recommended as your first source of stock if you do not have experience.
The important thing when starting is to specialise: choose a segment (diesel compacts, petrol SUVs, budget runabouts) and learn how to buy well in that niche before diversifying. If you want a more complete analysis of supply channels, you can find it in our article on where dealerships buy cars.
Basic tax: VAT, REBU and taxes
Tax is one of the areas that causes the most confusion when starting out. The two concepts you need to understand from day one are VAT and REBU.
General scheme (21% VAT). This applies when you buy a car from a company that issues you an invoice with VAT itemised (leasing, fleets, other dealerships under the general scheme). When you resell it, you charge 21% VAT on the full price.
REBU (Special Scheme for Second-Hand Goods). This applies when you buy from a private seller or from a professional who has not itemised VAT. You are taxed only on the margin (sale price minus purchase price), not on the total. It is the most common scheme in used-car buying and selling to private buyers and the most advantageous for transactions with end consumers.
You must notify the Tax Office that you operate under REBU when you register (form 036). In addition, you are required to keep a separate record book of REBU operations and to issue invoices in the correct legal format (without VAT breakdown, with an express mention of the scheme). To understand properly when to apply each scheme, see our article on when to use an invoice with VAT and when to use REBU.
Other taxes to keep in mind: Corporation Tax (if you operate as an S.L.) or Income Tax (if you are self-employed), quarterly VAT (form 303), declaration of transactions with third parties (form 347), and Transfer Tax (ITP), which is paid by the private buyer in private-to-private transactions (not applicable when the seller is a professional issuing an invoice).
First steps to sell: portals, website and visibility
Having cars in stock is useless if nobody sees them. From day one you need online visibility.
Car portals. Coches.net, AutoScout24, Wallapop and Milanuncios are the main channels where buyers look for used cars. Publish your cars with quality photos (clean background, good light, every angle), detailed descriptions and competitive prices. Do not skimp here: an advert with dark photos and no information loses clicks to a well-presented one.
Own website. Having your own website with updated stock adds professionalism, allows you to capture direct leads (without relying only on portals) and improves your local ranking on Google. A website showing your cars with filters, photos and a contact option is enough to get started. If you want to know how to set up your dealership website, we recommend our article on the benefits of having a website for your dealership.
Google Business Profile. Create and optimise your Google listing with photos of the premises, opening hours, phone number and reviews. It is free and it is the first thing that appears when someone searches for "used car dealership in [your city]". Positive reviews are gold. If you want to know more, we recommend our article Local SEO for Dealerships: Position your dealership with Google My Business
Centralised management. If you publish on 3 or 4 portals at once, doing it manually eats up hours every week and creates errors (different prices, sold cars that are still listed). A management system that centralises stock and synchronises it with the portals saves you time from day one.
Common mistakes when opening a dealership
Buying stock without calculating the total cost. The purchase price is only part of it. Add reconditioning, paperwork, insurance, transport and financing costs. If you do not calculate all of this before buying, you do not know how much margin you really have left.
Not checking the car’s paperwork before buying it. Liens, title retention, expired MOT, unpaid road tax. Buying a car with hidden issues can block the sale and cause losses. Always request a DGT report before closing a purchase.
Underestimating fixed costs. Rent, insurance, utilities, software, portals. Fixed costs add up quickly. If you do not make sales during the first few weeks (which is normal when starting), you need working capital to stay afloat.
Not having an invoicing system from day one. Issuing invoices incorrectly, mixing REBU with the general scheme or not keeping purchase documents are mistakes that the Tax Office can penalise. Set up your invoicing system before making your first sale, not after.
Relying on only one sales channel. If you only publish on one portal, you are limiting your reach. Diversify from the start: portals, your own website, social media, Google Business.
Conclusion
Opening a used car dealership in Spain is viable with a moderate investment if it is done with preparation. The legal procedures are manageable, but the difference between a business that works and one that closes within two years lies in the operational decisions: buying with judgement, controlling costs, invoicing correctly and building a management system that allows you to grow without drowning in administrative tasks.

Frequently asked questions
How much money do I need to set up a car dealership?
A realistic start with 5-8 cars in stock, functional premises and basic tools is between 30,000 and 60,000 euros. The biggest item is the initial stock. If you start with cheaper cars (below 5,000 euros purchase price), you can begin with less investment, but the margin per unit will be lower.
What licences do I need to open a vehicle trading business?
Town Hall opening licence, registration with the Tax Office (form 036 or 037), registration with Social Security, and registration as a professional operator with the DGT in order to carry out transfers. If you operate as an S.L., you also need a notarial deed and registration with the Companies Registry.
Can I open a dealership from a car park or without premises?
It is legal if you comply with the activity licence and local regulations in your area. Some municipalities allow vehicle trading activity on outdoor plots under the right conditions. But without presentable premises, the professional image and the ability to attract walk-in customers suffer.
Is it better to start as self-employed or as a company?
If you are starting on your own and with little stock, registering as self-employed is quicker and cheaper. If you are starting with a partner, with significant investment or with a view to rapid growth, an S.L. gives you more asset protection and can be more tax-efficient in the medium term.
How do I get my first cars to sell?
The most common sources to start with are direct purchase from private sellers (Wallapop, Milanuncios, contacts), professional auctions (BCA, Autorola) and a network of other dealerships. The important thing is to specialise in one segment and always calculate the total cost (purchase + reconditioning + paperwork) before closing the deal.
