Spring-powered car model. Toy, I had more than 20 years ago. But I remember how it looked quite accuratelisy. It was drived by spring. (Pull back car, to stretch the spring and go forward pretty fast) 1:50 or 1:64 scale. plastic body and chassis, rubber tires. That thing on the back was a jet engine. Spoiler was moving. It was bought in the U.S. in the late eighties. I do not remember whether it was Matchbox or not, but it was the most beautiful and the most favorite toy. I had to come up with some details Update! I found this toy from my childhood. It's a vintage 1982 Takara Joy Hobby Car Penny Power Pull Back & Go. I have it again. Here is the picture! Modeled and rendered in Blender Sound: Audacity
