you should be able to get a used one for around $1500-2000.
There's a place on pond springs-think it's called Kenfield carts. I think they'll have alot to choose from. A few years ago, I bought an electric golf cart that was refurbished from the factory, lift kit, bigger tires, and has a back seat (seats 4) for $2600 from Lone Star Carts. I think they are on 620 now
