2wd have a look at the obvious 3, the xfactory x6, the team associated b4, and the losi xxx cr. 4wd have a look at the associated b44, the xfactory x5, Tamiya trf 511 or 501x, hotodies d4, or you could even have a look at my jconcepts bj4we in the for sale section right now
I race the x6 i 2wd, and about to start racing the 501x worlds in 4wd. the x6 has been a great car so far. no complaints, and parts are readily available in this country. if your on a tight budget, as previously suggested, have a look at the for sale section on here as there are a number of bargains to be had. Dont forget to have a think about the electrics too, lipo are the way to go these days, and brushless speedos too. it all mounts up!!! good luck.
