How do you know that this Spanish Registered Car is taxed?
I have two cars herein spain an dthere is no visable eveidence they are taxed/
Every April Alhama de Murcia Council take the tax for all cars in the area from the bank accounts.
When you buy a car the dealer or during the transfer process the council are notified .
The new owner has to be on the Padron register in order to pay the Tax.
To get on the Padron you should be resident in Spain for six month a year ?
If you buy a Spanish Reg car in Spain it has to be legally transfered not sure how you transfer a Spanish Reg car bought in the UK?
May be worth talking to one of the many agents here in Spain who specialise in car transfer and regitration before you buy?
