They won't be around much longer in Cozumel, I'd bet. The last factory making them stopped production 2 years ago so there aren't any replacements coming. Being around salty ocean air, and the beating a rental car takes anyway, I can't imagine they'll last too long. I'll enjoy driving them as long as ISIS has them, though! I got an email from them today that my convertible bug reservation is confirmed so they have at least one left!
They paint them all sorts of colors. I've had black, pastel orange, flamingo pink, candy apple red, sun yellow, metallic blue, and lime green that I can remember. Some repeats. Never had white, though. Waiting in the office to bring the car around, we try to guess which color it will be.
