Question 1

Where do the seized cars put up for auction come from?

Accepted Answer

Passenger [vehicles](/en/subastas-publicas-vehiculos) auctioned publicly originate from seizures of individuals or companies for unpaid debts. These debts can be automotive finance loans, bank foreclosures through the courts, or unpaid taxes owed to the [Tax Agency](/en/subastas-hacienda-aeat) and [Social Security](/en/subastas-seguridad-social). This section focuses exclusively on passenger vehicles (hatchbacks, saloons, estates and SUVs).

Question 2

How much can I save by buying a car at a public auction?

Accepted Answer

Acquiring a seized car can yield discounts of 30–50% compared to second-hand dealers or the traditional used-car market. To ensure the purchase is profitable, calculate your maximum bid by subtracting Transfer Tax (ITP), any outstanding road tax and the cost of a mechanical inspection, as the vehicle is delivered without warranty.

Question 3

Can I see, test or start the car before bidding?

Accepted Answer

As a general rule, no. Seized passenger vehicles are usually held in sealed municipal or judicial storage facilities and are auctioned under "as-is" conditions (in their current physical and mechanical state). Although the auction notice sometimes allows an exterior visual inspection, you will not be able to start the engine or test-drive the vehicle before placing your bid.

Question 4

What is "retention of title" and what legal risks does it carry?

Accepted Answer

The biggest risk when buying a seized car is retention of title (reserva de dominio). If the previous owner purchased the vehicle on finance and did not finish paying it off, the finance company retains this block, preventing you from transferring ownership at the DGT even if you win the auction. subastAI's AI cross-references the file data to alert you to this and other blocks before you invest.

Question 5

What formalities must I complete after winning a car auction?

Accepted Answer

If your bid wins, the court or administration will issue an official award decree (decreto de adjudicación), which replaces the sale contract. With this document you must pay Transfer Tax (ITP) in your region, request the cancellation of prior seizures at the Movable Property Registry, and then go to the DGT to register the car in your name.
