I finally got one this last fall, a gas powered Yamaha G1 (two stroke).
I couldn't pass it up for the price of $500.
The guy said had been running, but I doubt it ever ran recently.
After checking the compression which was about 10 psi I decided
it needed a top end kit (piston, cylinder, etc).
The kit was $225 and after installing it and a few other parts ($275 in all the parts total) I have a good running gas golf cart.
I've pick up some deals on new tires for it too, which I was actually working on installing a few minutes ago in the garage.
All in all I have less than $900 in a good running gas powered golf cart so I'm happy.
Here's a pic I took just after getting it running.
At some point I'll probably paint it and make it a bench seat and add a rear seat.
