While looking up Cushman for manual transmissions, I came across this interesting fellow; a Cushman 7 Passenger Mini Van, which is technically a golf cart.
The first link has heat and A/C with a 3-speed transmission but only two pics. The second link has more pics, but just says gas engine. The second links pics show a shifter, so there’s that. From the looks of, it’s wider than a golf cart, but just has a really small engine. It’s adorable and I want one now.
