I do not see any signs of repairs or replacement parts, so it must have been played with gently. Overall, this toy is in good to very good condition. It might clean up to a higher grade.The wind up motor still works but, is a bit weak. At least I think it is. I wound the spring 3-4 half turns, which was enough to spin the rear wheels while I was holding it. That was good enough for me. The key and the 2 piece box are German made quality reproductions. I do not know the exact origin of the 4 figures included with the car. The item "1937 Germany TIPPCO Der Wagen Des Fuhrers Mercedes-Benz 770 Tin Wind Up Car" is in sale since Sunday, August 26, 2018.
