Sam, I hate to put a downer on your idea but I have, in the past, been involved in such schemes. It has ALWAYS ended in tears. I even had a boss who gave us two mini-mokes to get us around in Barbados. Maintenance and insurance was all taken care of. All we had to do was put petrol in the tanks. Sadly, there is always a lowest common denominator in every society and some of them couldn't even find the fuel cap.
Buy yourself a banger and keep it there for your own use and for very close friends.
