I'm not into RC cars myself.
However I did buy a Kyosho PureTen GP Alpha 3 Nitro RC car at a car boot sale in the summer for £18 as it was so cheap, it was almost brand new, all I had to get then was the fuel. I tried it out at the local park and I couldn't believe how fast it was and really easy to control, it was great fun especially with dogs running after it, although I would never buy a new one.
