This question comes up time to time,
I personally will not go the cheap route again, -i've done it several times and has always regretted it. Cheap cars are cheap for a reason, -poor fitment, quality, parts, you name it. I personally do not care for anything from 3Racing, I find that there tolerances are not very good. I don't have 1st hand experience w/ the Xpress $100 car that many on this thread have mentioned so its possible this car is an exception??
Personally I'd recommend getting a used, Team Associated TC7.1 -its a simple car, easy to work on, parts are readily available and not overpriced. If you do go used, do yourself a favor and tear the car down completely then clean and rebuild to the factory spec's.
