I recently got a 1987 Coupe Deville. It has the optional simulated convertible-style vinyl top on it. I was wondering if it would be feasible to install an aftermarket sunroof in it. Different people have told me it's not really a good idea, also these people don't really know much about cars, especially these ones.

Any input would be greatly appreciated it. I always liked a moonroof on these cars, just wondering if it would be a good idea to install one that isn't a factory GM option.
