In response to the one no im not stupid enough to do this but I was discussing this with a mate last night who reakoned you could because they look the same. But I pointed out the whole document thing to which he replied, "well a few lies oopps ive lost my documents can I have some more then reg it as a cupra." This is all on the basis of importing it to Guernsey.
Anyway this was all bought up, because there is a Cupra R for sale on autotrade and I was getting insurance quotes and they were fairly high.
