This little car measures about 6 1/2 inches in length. I do not have a key for this.
It is a key wind car. I do believe the friction mechanism would work. The flip top will flip but you have to use your hand.There may be a missing or disconnected spring. There is not rust, but some normal wear for a toy of this age. There is a sticker on the front that will come off to expose the grill.
