If you don't want a 'starter' car then the Yokomo is not the way to go, it's a highly stripped down version of their MR4-TC SD car with some flashy wheels and body. I suggest the Associated TC4 followed by the Team Losi XXX-S, both of these cars are great drifters and come in several 'flavors' (i.e. sport, team, factory team, rtr).

( Biggest the site had ) Yokomo drift chassis.

Team Associated TC4 ( Team Version )

Team Losi XXX-S ( Sport RTR Version )
Just keep this in mind, Yokomo's products are made in Japan and don't seem to have a very long 'shelf life' here in the states. Whereas the Team Associated and Team Losi line of cars have years of support and 'shelf life'.
