I've been doing Upholstery for along time and one of the first areas I learned was Vinyl tops. I don't think there's a car made with a solid roof panel I couldn't put a top on. Astro racer is absolutly right about the top holding in dampness. If you live in a damp or humid area and don't store the car inside ... I would forget the vinyl top, also I think a canvas material (conv. top ) would hold up better for you guys as it is alot more weather proof , at least on the top side. The other thing is the prep work for putting on a top is very important to the top material and or foam to seal up properly.
