I actually have driven one that belonged to someone I was working for ...but I didn't go very far .........I put an electronic ignition conversion on it and it has slant six ....but I could not drive it very far because it didn't have any plates or insurance....this one is a 100 so its shorter.
I thought It was an ok ride, wasn't the most comfortable thing ever but even at my height I could still drive it. turns were interesting :D
