Not all cars will wheelie,not even if maxed. I find great wheelie success with a 03 Mustang,an RX7,and a 67 Camaro. Max out any of these 3 and you'll be doing wheelies like crazy!
For drifts...use a maxed out Dodge Challenger,Rx7,or Chevy Chevelle. I can score over 8000 points per drift with any of these 3 cars.
For straight drags...use a maxed out Cad CTS. She'll blow the doors off any old school muscle car.
For grips...I find good success with the Beemers. They are fast and handle nicely. The Beemers are also good for speed races,due to their speed and impressive handling.
Drive it like you stold it!
