The base vehicle was a gijoe "monster blaster apc". Everything except the front and the rear fenders was removed and replaced with either Starcom parts [there's two H.A.R.V.-7 cockpit parts as well as a working cargo bay from Starmax Bomber] or rebuilt from scratch using a gluegun and cut-up CD cases [thanks for the tip Ward]. The outside details were sanded off/ filled in with modelling putty. The gun turrets are the lower legs from a Transformer Beast War gorilla. That's about it.
