Those HPI Cupracers are allright. Remember though that they are a bit different scale than most RC(drift) cars, they are M-chassis scale as its called. If you want it just for fun they are cool as you can get lots of awesome retro Japanese bodyshells for it. ABC Hobby sells a lot of M-chassis bodyshells like the AW11 MR2, S30, 510, TE27, TA22 etc. If you want to do competitions its not a good choice as they aren't legal anywhere and tire choice is limited.
If you need to know anything about RC cars you can ask me. I've been doing it for years. This is my RC Drift team: http://www.facebook.com/wreckitsideways
