A while back when I was deciding between an M3 and Supra TT, I got quoted £500ish on the M3 (Group 19) and £300ish on the Supra (Group 20, more power, Jap, etc).
Many more M3's have been involved in claims than Supras.
So a run of mill car stands to reason will have had more claims than a rarer car.
They go on amount, not amount per 100 or similar which would make sense...
