Cheers for the reply, any info I can get on the different options is great as it's all going towards my final decision
As for the cars, well amusingly all the three I posted were Darrians which is impressive seeing as of 107 entrants at the tour of epynt (first round of the British Tarmac rally championship) only 7 were Darrians. The grey one that I was helping out with is team promotive's t9 V6 which runs in class b12 FYI (basically the big boys class, fighting it out with the WRC imprezzas and fords and the likes.
