Mine was a used fleet model from a golf course. The local golf cart shop gets the used ones, cleans them up, checks them out, then sells them for a fraction of what they cost new.
Mine is a 2009 EZGO RXV, 48V, with an AC (not DC) motor. Very quiet, travels at 19.5 MPH, has a range exceeding 30 miles. Easily hauls 4 people up hills. Price was about $2500 several years ago. New, this model was $8K.
The upside is there's virtually no maintenance other than watering/charging batteries.
The downside is the batteries eventually fail (5-6 years in my experience). I replaced mine again late last year. I bought Trojan T1275 batteries. The cost with core exchange, state fees and taxes were $772.54 for all 4 batteries.
It has enough power to pull a truck, which I did once. But I often use it to pull a 5x8 utility trailer filled with yard waste, or a couple of yards of mulch.
Electric carts are permitted at Disney's Fort Wilderness (gas are not), and at many of the FL State parks.
