No folding bike I have ever seen could be described as a good choice for a 300 pounder. Some of them (e.g. Swift Folder, Ritchey Breakaway) would survive; many would not. Bikes with a sideways folding hinge in the middle like the one in the picture start out crappy and go downhill fast (figuratively, not literally). A good sign of better than normal integrity is if the folding mechanism uses the seatpost as a fixing pin.
Also, to the nearest approximation, any bicycle named after a car is a horrendous piece of crap. I think BMW and Porsche both made gimmicky, overengineered but decent quality (and very expensive, and rare) bikes in the past. Other bikes branded as cars (Jeep, GMC, Hummer, Cadillac, etc.) have been super nasty BSOs (bicycle-shaped objects) akin to the other "bikes" at your local big box department store.
