The Incident has a plastic chassis, the Incident pro has the same plastic chassis but moulded in silver plastic to make it different. It isn't alloy.
Standard car had batteries mounted across the rear of the chassis, shaft drive with motor mounted in front of the centre mounted diff, just like most modern shaft drive buggies. Monoshock suspension and four wheel steering.
The pro version came with alloy wheels, alloy steering knuckles and front UJs, the standard version hd plastic wheels, plastic knuckles and dogbones all round.

It was heavy and overcomplicated, anyone who raced one threw away the chassis and made up their own from fibreglass or carbon sheet, made up mount to fit 4 shocks and replaced the centre diff with a simpler gearbox.
