Not to hijack the thread, but always wondered why gmp or any other manufacturer has never made a t-top version or a sunroof version of these cars? The convertable is a nice touch but none are even in existance? I think molly or someone out there has made a 1/18" diecast t-top monte ss only in the 85 year which is nice as hell. Hopefully someone will do a t-top GN one day and also a 84 GN model. I'm also still waiting on someone doing a diecast or plastic RC buick gn car.
