There's probably close to 20 different variations of the 62 that hot Wheels produced, the yellow one is just the latest. There are several of them that are getting harder to find and getting up there in price.
Here is a great site to show the different ones they made. Just click on the black font "IMG" next to the Custom 62 Chevy in the Car name column to see each model they did.

This is probably the best diecast website to buy from:
thetoypeddler.com Prices are generally much lower than eBay and you don't find as many flakes. Do a search and you can find them, usually only a couple buck + shipping. 99% of the sellers will combine shipping so that's were you can make it a better deal.
