Hi Sandie
Welcome to the LSFL Forum!
As far as I am aware if your cars are Spanish registered then there is nothing to do! Gran Canaria is part of Spain.
If you have a look here you will find lots of info on importing cars [url]http://livespainforlife.co.uk/default.aspx?id=7
and if you are still unsure then try this website which is dedicated to motoring in Spain
[url]http://www.spainvia.com/
It has all the up to date info on it, you can also write to Brian Deller who wrote the site himself at Round town News, one of the Costa Blancas leading expat newspapers

Good Luck
Kind regards
