The three wheeler 4 door Jolliet looks like its trying to fall over standing still. Heaven knows what it would be like if it ever saw a corner. Never seen one before. Probably just as well.
In my youth a friend of mine had a Reliant three wheeler, because he could drive it at sixteen. That spent more time with one of the rear wheels in the air than not, and had more gravel rash on its sides than paint.
His parents wouldnt let him ride / have a motorbike because "they were too dangerous"....but were happy to let him loose in a Reliant 3 wheeler. Go figure.
