I rang these guys yesterday and was actually amazed at how much hard work it was.
The guy I was speaking to on the phone was really struggling to understand my modification list. When I mentioned 'boost' he had no idea what that meant.
Then I had to explain boost pressure and also explain what samco pipes were.
Needless to say I don't think i'll be insuring the car with them as he also didn't even know what a Renault 5 GT Turbo was.
