Well, if you're familiar with Nitro engines, then get your preference. Any 4WD car will do. However, if you're new to R/C all together, or just aren't familar with gas motors, I'd recommend an elec. I'll let someone else do the chasis recomendations cuz I don't know of too many. MR-4TC and Traxxas 4tec are the two that I'm running.
