A couple things to consider:
1. Will you be buying Gas or Electric?
2. Will you be modifying the cart at all?
3. How well has the cart been maintained?
If you are going
GAS: We recommend going fuel injected. And if you can afford it, choose the Yamaha QuieTech powered models (very quiet gas carts).
If you are going
ELECTRIC: Any cart will do, as long as maintained well.
If you will be adding modifications to your cart (rear seat, windshield, etc.), then going with a cart that is
a few years older is best (like 2010-2016). The reason is, the longer a cart is on the market the more aftermarket
Golf Cart Accessories that will have been produced for it. Many newer carts don't have lift kits or other accessories available for them.
Our personal shop cart is a 2007 EZGO TXT that is maintained like new. Lots of mods available from all aftermarket manufacturers for it.
Here is a golf cart buyer's guide we also hope helps:
