my top 3 would be
bmax4 iii (great car for the money it is now and has gear diffs)
durango 410 v4 (again good car for the money and you can pick 2nd ones up for good money, also gear diffs)
kyosho zx6 (this is the car i run, only reason i placed this car 3rd and not top is price, ive had the bmax4 iii it was great!! this car comes with ball diffs but ive changed mine to gear for an extra £104
