Okay, so you wanna start a small business and make a few bucks. And you want unusual to a degree.

Then get off your backside and get yourself a Rhoades Car http://rhoadescar.com/lobby.htm

You can sell advertising space on it and park it. Sell advertising space and ride it around. Sell advertising space on it and ride other people around for a small fee - like chinese rickshaws. You can hire them out for others to ride around a park somewhere. You can get the pickup version and be a mobile store of sorts. Maybe doing the rounds at some public event selling stuff from the back. You can hire them out to others for a daily/weekly fee so they can charge people to go for a ride. You can... think of other ideas yourself.

Or you can toss this idea aside and do something else.

Your call.
