When I had a Smart car and a scion x-box, I could park both cars and 1 cart in the garage and leave 1 cart outside.
Now that I have a Buick Rendevous and 2 carts, I find it easier to leave the car and 1 cart in the driveway and park the other cart inside to get charged up.
I have had the buick and a cart in the garage and if I got rid of some stuff in the garage I would also be able to park the other cart inside.
It really depends if you want to have some extra room inside and not have the hassle of trying to back out of an already difficult garage/drive that the cyv's have.
I prefer to park at my neighbors when they are up north for the summer
p.s. A cart will not fit thru the gate ..........if they did, I would keep one back there at times.
