New E-Maxx needed w/ GMaxx Chassis?

My stock 4-month-old E-Maxx is pretty thrashed. I would like to build a nice project out of a GMaxx Chassis, Suspension, Motor Plate, and a Brushless Motor & ESC. My question is:

Should I buy another E-Maxx to get most of the parts or just start from scratch? It seems like I wouldn't be using very many parts from a new E-Maxx and most of the ones from the existing car are thrashed. I can't imagine the radio, receiver, wheels, etc. have much resale value.

I'm also going to try to build/find a buggy or stadium body to fit and get the overall height down.

Thanks in advance for any advice.
