I'm not sure if its Sportsmobile built, but I really like it. The flooring looks like the loncoin flooring they offer, but the stock headliner was used and there aren't any light fixtures that they normally put in. The ad says 1996 and 2006, but I'm guessing its a 2006 based on the mileage.
Looks like you could fit a dirt bike or something with the gaucho seat up.
I talked to the owner. It has a SMB pop top but the top, as well as all the conversion, was fairly unprofessionally done by previous owner. It all works ok but not at all up to SMB specs.
