I bought a used golf course lease return 2019 48v EZGO from JB Carts in Keller a little over a year ago.
https://jbcarts.com/ Justin (the J in JB) was easy to work with. It has been good, I had to replace the batteries, but I was warned they were not in the best shape. Found some less expensive Interstate batteries that are not the best, but the range on the cart is still probably 20 miles.
Bought to take to my families farm house but my teenage daughter has embraced it for running around the neighborhood.
He has reasonable prices and parts, and his inventory is constantly changing.
I had them add lights and raise the speed settings. I lifted it with a cheap kit off Amazon, (lift kits can be cheap and simple, or fancy and expensive) and added bigger tires I bought from them (they had the best prices I could find). Added the back seat that also flips down as a cargo carrier. I have also replaced the brakes. I need to replace the rack and pinion steering.
All in price after batteries was a little under 5K. Golf carts are expensive, but they are easy to work on and the parts are cheap if you are willing to do the work yourself. I have not had any electrical issues.
I have removed the logo and number and added fender flairs since this picture was taken.
