If I were looking for a used cart from a dealer I would check Grandma and Grandpa Village Buggies on 441 north of 42 on the right side. They are very nice people. When I was last there, they said they buy all their carts from a course in Virginia where they use to live when the carts are just 1 or 2 years old. Grandpa does all the work himself and they look brand new sitting in the showroom.

I would also check Villages Discount Golf Cars on 466 just east on Morse in the tan colored shopping center next to Birdie Golf store. They have excellent reconditioned carts and say they use better products and parts than other dealers. The customer service is usually rated top notch by most who go there.
