Cant beat a mini cooper (tamiya) m-02 chassis, stick a novac ESC in there with a 19 turn motor, and youll be well away, Just keep alot of pinion gears and gear sets spare, as they wear out rather fast :D
All good fun on a budget,and they dont half drift like a beast (Y)

EDIT:
Tamiya doa ready built version(no differnce, just more pick up and play version for 150 of your finest sterling pre built ralyee stylee mini
OR
Theres the build it yourself kit, which comes in airfix type part sheets, If you go for this option i strongley recomend you go for the electronic speed controler version (less maintenence, more room for upgrades in the furture)
