As a top 10 Formula Drift professional experienced driver, and the 2005 Rookie of the Year I would have to say out of all the delightful vehicles I have been honored to drive, the best car to drift is somethign you've rented.

1) Drifting breaks things
2) Drifting kills tires
3) Drifting can cause a wreck
4) Drifting is illegal, but not a crime
5) Break it? not your problem, you have $8/day insurance
6) Rental cars come with rental tires.
7) See #5. Remember, 80% of drunk drivers leave the scene of an accident
8) Rental cars come with rental car looking vehicles that when you cover the plate, probably wont get traced back to you
9) Rental cars come with free roadside assistance, and they will replace your tires for free if you "have a flat"
10) Its a rental car.
