Do the main car dealers take trade-in of Englosh cars?

I have a 2 yrs old Vauxhall Corsa and was wondering whether anyone has experience or knows about the main car dealers, such as Opel or Renault with regards to trading in my British registered rhd car for a Spanish plates lhd? I was planning on a trip to Velez Malaga to see but thought I would put it to you helpful people and see what comes up.

In the UK this is what I would do but I know things are diferent here.  I don't want to go to the trouble and expense of putting Spanish plates on it.

Any advice gladly received.
