If your question is referring to the golf cart when you wonder what "as is" means:
You're getting it as you see it. Whatever might be good or bad about it - - - it's yours. You'd have no recourse to go back to the seller to say, "Hey, (this or that) doesn't work right" or "The batteries in this are just about gone" and so forth.
If you're concerned about the condition of the cart, you're doing the right thing by trying to find an appropriate person/company to check it out for you. They can at least give you a pretty good perspective on things that might currently need addressed or will need some attention in the future.
But if you've already signed the deal for the home in Duval and the as-is cart was included in that, it's probably too late to go back to the seller if the cart's condition turns out to not be to your liking.
