The first 8-9 races are pretty easy to win. I used a Minolta and won all but New York easily (came in 2nd by < 10 seconds). However, around then you will be around 1500 or so miles and the chassis will start going away and you will find your dream car becoming a nightmare in handling. The rest of the races will be white knuckle time. That does not happen with the F1 car, which never needs a chassis refresh. Hopefully you will already have close to enough points to win the championship...
