There are a lot of cars to choose from, any of them will be fine as you are learning; for beginners it more about driving under control rather than subtle tuning.
Every beginner breaks parts, get the car easiest to get parts.
As for all the brands, you can't go wrong with Associated. Everybody carries their parts and their designs are solid, their finish leaves a little to be desired, but the parts finish won't make you finish higher on the grid. The Corally's and X-Rays are more works of art - fantastic finish to the parts and wonderful to work on. Reward yourself with one of those as you graduate into the higher classes.
I learned on a TC3, graduated to a Corally Phi, went back to TT-01's to show people you can run with a $100 car (I only recommend this one in silver can racing, the gear ratios don't work for 17.5 and 21.5 racing), have been back to racing the TC3, and am considering getting the X-ray for going to this years Vegas race.
Get the car that has parts in stock, don't go expensive now, save that as a reward for latter.
