Flame,
Don’t know if you’d consider used, but that’s what I did. I found a 2012 Honda Big Red. It only seats 2, but I put a second seat up in the bed that folds up out of the way when not in use.
It is shaft drive as opposed to belts, fuel injected single cylinder 650 cc engine used on their motorcycles for many many years. It has proven to be very (Honda) reliable. Goes anywhere. At least I haven’t been able to get it stuck yet, and hauls everything I need. Not all that fancy to look at though.
