If you had a motor,I would say its worth it.I had two of themback in the late 90's,i still have one thats modified to electric.Heres the cons of that truck.
Thin chassis with almost no support,it flex's alot and will strip you spur gears,Plus if you hit something head on the chassis will bend out of shape easily
The Composite spur gear is weak and strips easy,I dont think there was a steel replacement,I tried to convert mine to a Traxxas Rustler spur but the traxxas was too large,But im sure theres a spur out there somewheres to fit.
The engines didnt last long and ran hot,both of them,Im a very experianced nitro guy.If you get a new engine and you stay away from high output engine,like the Traxxas 2.5...it will kill the tranny/spur
Goodluck
