Hi I know this post is a few months old, but, if you take your own car that is fine, the big but is, if you have a bump or your car is old and needing to be scrapped, you can't.........you have to pay to get it back to the uk !
They will not crush or scrap a uk registered car "FACT" !
I have worked in various parts of Greece and I know this to be true of any of the Islands. And there is no way you will be bump free, it's totally wacky races everywhere you go !
