I've been with Adrian Flux for three years now. low price and great to deal with, thouch wood never had a claim. I know they do some great deals with other car clubs.
I've been with Adrian Flux for the last couple of years, very competetive prices, will insure modified cars, and were the only insurer I came across who would give me a substancial discount against my no claims bonus when I got my V6 as a second car. Sounds good if there is a further discount when it becomes due again.
