get a used cyclone WCE, the money you spend upgrading cheaper cars will be more than just goin for the good stuff from the start. Its a very capable car, I drove it when I was still a noob and it worked great for me. Very durable too, although make sure you use the "hard" version steering knuckle and c-hub, I have only broken a few suspension related parts in the 2 years ive had the car.
Plus they are very easy to work on, and alot of pro drivers have used the cyclone (it was world champion after all), so there are plenty of setup sheets out there to get you started. Just remember, dont skimp on the important things when it comes to buying a car, or you will end up payying more in the long run. Good luck on your shopping!
