For bodies i think some of the proline shells will fit that are made for other vehicles, you should go to your LHS and see what they can match up to your vehicle or you can order some clear bodies for your vehicle as well that are made by duratrax.
As for motors, I would look into getting a good 19 turn motor unless you plan to race. For racing you will want a stock motor to start with. Look for a motor that is more torque based.
