I raced nitro sedans for 3 years and I think the NTC3 is the best buy for the money. You can find tons of parts online and maybe you r local hobby shop. If you want a good quality car with good handling, I'd go for a Mugen MTX3 or 4. Parts are hard to get except online but they are nice cars if you are competing. If you are a parking lot basher, I'd go with the NTC3. Less body roll because the CG is low. The HPI's and 4 tec suck unless it's your first bash. Then you will learn that you should've listened to me. I've owned both a 4 tec and NTC3 and I wished I bought the NTC3 in the first place. The 4 tecs belts slip and the 2 speed tranny gets oil in the one way bearing and slips from then on. The bearing on the starter also slips after a couple of months. I put an HPI SS together but after seeing how crappy it was, I sold it without even driving it.
