My choice really isnt fair but fun as hell. I ve got a wrx running 600mph+ and a cammaro race car running high500's but the most fun is the beetle w/awd running 400s on dirt tires flying through tahiti maze tracks, yeah I know cheat codes arnt fair but if you can hack ps2 games w/ game shark its still funny to see a car go a good 10 feet of the ground in a dirt hairpin turn at over 200mph
