By the time this model came along, Mattel was already in process of shifting all production to Hong Kong, this model was never made stateside at the Hawthorne factory. Emulating the vinyl roof treatment popular on cars at the time (itself mimicking convertible "soft tops"), many of the models closer to stock in the redline line up got the blackened roof treatment, but depending on the model as to how often it was applied. In the case of the Roller, black roofs are not all that common, though I wouldn't call them rare.

In typical Hot Wheels style at the time (as seen by the green Roller hiding in back), spectraflame paint was the norm. I think the Roller was the first non-racecar to be painted in enamel, if not first certainly one of them. Seems Rolls Royce the company took umbrage to Mattel dolling up their vaunted model in candy colors and ordered a cease and desist, and from then on it was only available in enamel gray, though it was only in the line for perhaps a couple years. Most kids at the time wanted the muscle cars anyway, and even today the Roller doesn't get quite the same respect as the Mustangs and Camaros and other comparable models.

Still, for the day and time it is a respectable model.
