Check out HPI's E10 chassis. It comes with the extra parts to move the motor/electronics around so you can make it a rear motor or mid-motor setup, this way it can be a drifter or a touring car, all in one box.

I'm planning on getting the Vaughn Gittin Mustang soon, mainly because it's the new body Mustang, and if I suck at drifting I can just swap the internals around and make it a standard touring car!
