moving water freezes much slower than still water. so a solar fountain type that cascades the water will not freeze as quickly as one without a fountain. the sun itself is a solar heater, isn't it.......the obvios problem is providing heat after dark. the only way for a solar heater to work after the sun goes down is to have some way to store power, so my guess is a solar heated birdbath doesn't really exist, and if it does it would cost you a pretty penny

If I was trying to do this I would buy a basic, general fountain kit and install it in whatever you have in mind, whether a real old car or perhaps a pedal car toy or the like. Also, if you have a 'cement artist' in your area, one who specializes in birdbaths, urns, and --maybe they could custom cast a car for you. good luck

If you're worried about maintenance, forget the fountain. You have to refill them when they get low on water, unless you connect it to your water system and let it refill as needed. And if you are in a freeze zone, you will have to winterize the fountain, which means draining it and putting it up for the winter. Or you could hire a landscaping service to take care of it.
