When we ordered ours from the Villages Golf they gave us a loaner until it came in.

A little first aid kit - for attending to grandkids bumps and scrapes while dancing at the Squares.
A hand crank led flashlight - for exercising on the road and reading menus in dimly lit restaurants.
Set of small bungee cords - for tying down those plastic shopping bags from sliding around.
A multitool - for emergency repairs on reading glasses.
Corkscrew/churchkey - for spontaneous Square entertainment picknicking.
Suntan lotion - for visiting northerners first few days.
A 10,000ma charged phone/ tablet recharger - for getting a charge back in your life.
Umbrella - for those sudden 15-minute popup rain showers.
The Villages Map - for finding all the clever ways they name roads without calling them roads.
Old towels - for wiping off Square chairs and when an umbrella is not enough.

upgraded seats,led lights around headlights, trays front and back are great for storage,

**** Aide. It's like AAA for golf carts. If you get a flat tire or run out of gas or your batteries quit, they come and pick up your cart and bring it where ever you'd like. They may even carry a bot of gas.

It's very inexpensive (about $40 a year if I recall) and it can save you a lot of headaches if your fuel gauge is wrong or you get a flat tire or break down.

USB port if you use your phone for GPS.

I’m a little bit short for my weight, so independently adjustable WELL PADDED seats are a must have. Very costly, but your back will thank you.

Self cancelling turn signals would be awesome.

Windshield wipers - which would necessitate a different windshield configuration.

Gracie - LOL! and it looks like his play ball is stored in the back!
