I have an old electric '85 EZ-GO that I use to go back and forth to our 2nd garage down the street. Our street is private with a 15 mph speed limit, so I don't worry about being street-legal.
If I was going to get a newer cart - I'd opt for the 48-volt models. Mine is the typical 36-volt cart and is pretty anemic as far as speed goes....LOL! And I'd get a cart with a roof - most golf cart covers are designed for models with roofs. I DID discover that an XL-sized ATV cover fits my topless cart just fine. Since it runs and charges nicely for its age - I'll keep it until it dies....
