I would figure out what is most important to you, price, size, customization options, looks, RTR vs kit, parts availability etc. There are loads of RTR options these days that come with cool scale bodies (e.g. 4Tec 2.0, Fazer Mk2, V100, Apex2, RS4 Sport 3). The Kyosho being by far the best value of the bunch. If you start looking at kits, the TT01E/TT02 stuff from Tamiya is super cheap and quick to build. If you want something a bit more race car, and as previously mentioned, the XV01/02 or a TC01 should work. If you don't care much about having the ability to use all the standard 1/10 scale road car wheels/tires and bodies, you could look at some of the slightly larger cars (e.g. 4tec 3.0, 1/8 Vendetta/Infraction, QuantumR). If you want to go full blown fun mode, an 1/7 Arrma car is crazy amounts of enjoyment
Just be ready to spend $$ on tires
