I'm posting this here because I'm not sure where it fits.
Collectors might want to look elsewhere.
I've posted a time or two about battery powered cars from a company called Nkok. These cars are 1/32nd scale hard bodies with decent detail. These cars ARE NOT collectibles, these things are only suited to racing or playing. They are very low cost and quite durable. You'll really need to come up with your own chassis for racing but the existing chassis can be modified to work if you're just looking for a slot car to play with.
The major slot car companies all make very very attractive cars and most of the reviews on slot cars in this scale tend to focus on paint and accuracy. Well, I don't collect, I race. I want a body I can hammer but still looks like a car so lexan is right out of the picture. On another forum someone mentioned a local (US) drugstore selling cheap cars and I saw some on that auction site that didn't look bad so I went and bought some.
are some not too good pictures of one of the cars, the 1970 GTO Judge. There is also a '69 Z28 and 70 Chevelle SS 454 pictured.
These cars are an option for racers to try. You'll need to build or swap in a chassis but at least you have a body that can be hammered without worry.
