Here's a nice little set of photos from the Knotts Berry Farm Kit Car show. If you get past the first page, there are some pictures of cars other than Cobra replicas (especially on pages 4 & 5).

And if you are actually looking in to buying a kit car, you will probably want to look at Kitcar.com's consumer alert page, and make sure the company you are thinking of buying from is legit. There's a lot of fraud in the kit car industry.
