Karl,
Cut me some slack in that I havent even been able to drive it that far at one time without something breaking!!
Seriously, it has had as many test miles put on by the shops that have worked it than I have put on it(I added it up yesterday) Out of the 765 miles on the car now, it has had 375 test miles put on over the last 18 months and I have driven it just under 400.
