GEs Partio Carts
Are a wonderful appliance, take it from the only AW member that owns two of them, If you could afford the over $500 these cost in the early 60s have an outlet installed for less than $100 would not have stopped many people.
Overall it is probably far safer to use this appliance outdoors than a propane grill., I have used ours even during a down poor.
This is differently the ultramodern MC way to entertain outdoors. I would also guess that this one was repainted, it does look good in black but they should have painted the wheels as well.
