This is my first post. Just joined after looking on the net for some ideas and came across your forum. I purchased the GTO from a hobby shop and old mate said if I choose another id get $5 off. Not that he needed to twist my arm. Hence where the dodge viper V10 engine comes into play (original engine looked to small). After massaging the chassis and not putting the fire wall in the engine bay the V10 slotted in nicely. The bonnet fits on perfectly too. Once painted the model looks a cross between a HQ Holden Monaro and an XB Falcon Coupe here in the land down under. Will be looking at building more models in the future to include trucks as well. Found a half finished truck model that dad had as a kid so tinkered with that today as well.
