I happened across these pedal cars tonight at an old classic car website: http://www.oldclassiccar.co.uk/pedal-cars.htm. You can see other pedal cars at the CJ-3B Page: http://cj3b.info/Toys/ridingtoys.html
On a separate search I found a bunch of pedal cars for sale through http://www.prices4antiques.com . Unfortunately, you have to subscribe to find out the prices.
