Change of registered address for car

Hi.
Until very recently we owned a villa near Malaga.
We are now going to rent on short term. However, we still own a Spanish car!
My question is, can I give a UK address for the car?
Am conscious that any mail relating to my car will be sent to our old address.
The tax is paid by direct debit and I've just renewed the ITV.
Anyone got any suggestions around this problem otherwise guess I'll have to sell it.
Thanks Jeff
