On road (touring cars etc) or off road (monster trucks, buggies)
Are you bashing or racing? (bashing is throwing it off ramps, driving round parks and the like, racing is pretty self explanatory)
I'm guessing you want 1/10?
Do you have a budget in mind?
If you're looking for an off-road basher, truggy style cars perform well, the e-firestorm is a personal favorite.
If you're starting up, a tamiya tt01 is a great choice, it's very versatile and can be turned into a wide variety of configurations
