I am restricted to electric cart bc of the campgrounds I goto. They don't want gassers running around the camp ground at 2 am etc. Not all gassers are loud, but there will always be that guy to ruin it for everyone.
But there are electric carts that show up at ocean lakes running 40 also
So ya. He should get a cart that fits what he is using the cart for.
Just remember this new ethanol blend fuel they are selling is hell on carbs that sit for a long period of time.
