if your planning on just racing at club level (indoors) then ideally 4wd will be better, im new to the sport (and cant control my car to save my life) i went for a brand new FTX VANTAGE the car comes ready to run, although to play at club level you will need a better charger and another lipo battery
FTX VANTAGE £180 RTR from ebay (brushless version)
LIPO BATTERY £30 from ebay
IMAX CHARGER £35 complete from ebay........you will also need a set of new wheels and tyres for the sports hall to get some grip
WHEELS AND TYRES £20....SCHUMACHER YELLOW minipins or spikes
GRAND TOTAL OF £265 and once you learn to drive it should be fast enough....its still too fast for me
