I have tried something a little different - the '90 Nissan Primera GT. (costs 3,888Cr) Mine was in dark blue with Falken alloys, a real beauty to look at, and boy does it go! It slides a little and it only goes to 292hp max, but this is one really good ca that nobody has tried yet - it also has race pedigree, been in British touring car races since 1991.
Also try that underrated econobx, the '89 Mazda 323 Sedan..370hp max, can be lightend (w/racemod) to 895 kilos...is much better that it looks, and is a better, cheaper bet than the GTX, as you can actually get more power out of the standard FF Sedan than the 4WD GT-X. the GTX is also 200 kilos heavier.
