Your second sentence says it all. Just because you have something that you haven't seen on every street corner doesn't make it particularly rare or valuable. It sounds like you might have a decent cab. IF you can find somebody wanting it you might get a couple hundred dollars for it but anybody who doesn't really need it will not touch it for that price though. So if you want to sell it, put an ad in the swap meet section and see what happens. If you get no response in a few weeks start lowering the price.
