Buying cars in Spain - 4SaleinSpain.com:
Second-hand cars in Spain tend to be more expensive than in many other EU
countries as they depreciate less after the first two years than
say in the UK. If you intend to buy a used car in Spain, you should consider
the following:
The car has a current ITV test certificate, if applicable;
The chassis number should be the same as that on the registration document, which should be in the name of the seller when a car is purchased privately.
You must receive a `transfer of ownership' (transferencia) form from the seller.
When you buy a second-hand car in Spain you must obtain the following documents
from the seller;
1. Registration document (permiso de circulación). The Permiso de
Circulacion is the Spanish equivalent of the Registration document in the
UK and owner's details have to be changed when vehicles change hands.
2. The ITV test certificate plus the technical sheet 'Ficha Tecnica' and a photocopy. Again this should correspond to the vehicle number etc.
3. The road tax receipt and a photocopy and a receipt for the payment
of transfer tax (4%).
You have 15 days to register the vehicle in your name after purchase.
An important thing to do is to do a History check on the vehicle
you plan to buy. This is the Spanish equivalent to an HPI check in England
so it covers any fines, debts or outstanding taxes on the vehicle which
once in your name will be liable to you unless you insist the seller pays
them before you purchase.
If you do not wish to carry out the process yourself, then for a small sum you can arrange for the work to be done by a Gestor. These companies carry out admistrative tasks such as this and are widely available in Spain. The only piece of advice is to shop around for the best price and service as they will differ from place to place.
