Tamiya TRF-501X is a great car. Parts are hard to find in stock in your local shop so you will have to invest a little in parts from across the pond. But it is easy to drive and doesn't mind being over driven. It is pricey but it is a very strong car. It is hopped up when you buy it.
If you want a car where you can find the parts on the wall get a B44.
Good luck with what ever you buy.
