It's a question of "wants" and "needs"...
All of you "wanted" one, but no one "needed" one!
Being a guy that love the obscure, I have had my share of odd motors with wheels attached, so far just 2 and 4 wheels. Although back in the "day" I raced snowmobiles and had way too many of those.

So it really isn't needs, but wants.
At one time I had 10 vehicles that I had to insure. That was with just the wife and I.
