Here are five Schuco vintage wind up cars. these toys were played with and a couple are missing steering wheels. They definitely could use a cleanup some of them kind of work. However, these things are amazingly engineered. The large green formula car has an actual differential with pinion and spider gears. The micro racer turns the wheels by spinning the exhaust pipe. The micro racer has the worst tires. However, I’ve seen replacements on eBay. It also has a stop and go lever the gray one actually has a gear shifter with four forward gears and a reverse. The dark blue one has an SOS button on the back to make it stop and go. Plus it steers. Anyway, they all wind up and kind of do stuff. Comes with one wind up key that fits most of the cars. These cars are in found condition. I have done nothing to clean lubricate or fix them. So you’re gonna have to take a look at the pictures and see the condition of the toys yourself and see what you think. Thank you for your interest , bid accordingly and have a great day.
