Good experience to-date with a new 2011 Yamaha gas cart we bought over two years ago. Even though we're only in TV intermittently, we put a LOT of miles on it while we are there.
The only maintenance we've done is to change the oil per the manufacturer's recommendations/specs. It takes one quart - no oil filter on a Yamaha. I've taken an occasional look at the spark plug and the air filter as well - they're always fine and haven't needed any attention yet. I put fuel stabilizer in a full tank of fuel when we're going to be away from TV for extended periods of time to help keep the fuel from deteriorating. A battery maintainer (ex. Battery Tender) is used during those times as well. We've had zero problems with the cart.
I've also done other things such as checking tire pressures, alignment, rotating tires, etc. but those same things would apply to maintaining an electric cart as well.
We're happy with our cart!
