The Enzo is alright. Its the best car i have raced in it anyways, but its very tail happy and like an over powered go kart [makes sense i guess] but theres no TC on it so you will whellspin like mad.
The best car is certainly the Speed 12 but since you need all platinum to unlock it or a mate with a memory card who has done that already then you dont have much chance in getting it. Platinum cone challenges....no thanks.
Most people who have played the game for a while seem to race wither the GT1 or the CLK and seem to have developed a snobbery about the Enzo being bollox but i am able to give them a good race and can even win against some racers who literally have no life. I mean, rank 33 in Xbox live and i was winning on the the ring against them....well until i fucked up about 25 corners from home

haha 25 is more than most tracks altogether.
I was almost put totally of live on my first night. I joined a PGR2 game which was full of americans. A guy who sounded like 14 goes to me: "your not from america" so i respond "no shit sherlock" and this is just priceless...he then says "so what part of canada are you from?"
Luckily i have a little buddy list now, mostly scottish boys who seem to have a little more education or intelligence than that
The brits/scots whatever are a good laugh, although i think some take the racing way way to serious but thats how you get better i suppose.
