Hi Molleypeanut,
Welcome and congratulations on your new home! Yep, golf cart is next.
We bought a used cart from Carts and Clubs in Ocala. The Villages Golf store also sells used, as do individuals. An advantage of buying used from a reputable dealer such as the two I've mentioned, is they usually condition them well, are honest about the condition and will price them accordingly, I would think.
Another question is electric or gas. Gas has much longer range and low maintenance. However, they are noisy and can smell.
So, consider whether range is an issue for you. If you are a golfer and want to play all the courses, not just the nearby ones, and you might run errands in the cart before heading home from golf, it could be.
Whatever you decide on, enjoy tooling around TV in your cart. And enjoy your new life down here in Lower Paradise!
