Best is a tie between Viper ACR and Skyline GTS-T (FR)
My favourite is without a doubt my baby GTS though, she can drift even on racing softs but because I use a drag racing transmission trying to drift her is like learning to use the X1 all over again.
Favorite is my Pontiac GTO... sooo loud and beasty... My best is probably my Toyota Aristo Vertex Edition... It's got enough power to leave a trail of smoke from any gear yet even at low speed, low throttle it's manageable
