i think the 205 would be the best bet, I would love to get a honda but in 6 months time when i want to make it faster i would never be able to afford to tune it. I know its awsome out of the box, and Evo mag voted it the best fwd car ever but i think after some time i would want to go faster!
The rs2000 would be a nice but im looking for a power to weight ratio of 200bhp per ton, and to get this without spending the earth on the engine would need to shed around 250-300 kilo's of weight which i think is a little unrealistic.
