Too bad that's not true about Gran Turismo 1. I think the worst car was the CRX '91. It's not that great in GT1 either. I must say though, I like the Mugen CRX Pro. II.
Since I have been playing GT1 for the past couple of weeks, I have thought that is it better than GT2 but then GT2 offer a lot more but in terms of game play I would go for the first.
