I tried to buy one in '84 or so from a young couple in a trailer park. Took it for a test ride. Agreed on a price. Then they informed me they didn't have a title. After listening to them tell me how easy it was to get a title, I told them to go get one and call me. Never heard back of course. Pretty sure it was stolen.
Always like them. Very rare. If you want one and can find it, it will probably serve you ok. For dirt work an SL 350 twin (Honda made an SL350 single too) is capable of, you'd probably be better served by any number of '80's or '90's street legal thumpers for less money.
