Undefined VW beetle

I want to make some car stamps, mostly classics. I think those would make really neat cards. I just need my husband's help to find some great images if cars - easy enough to carve.

But I managed to find a fairly simple image of a Volkswagen Beetle. And even if I say so myself! I think this stamp turned out pretty good

Again, at the top is the printed image from internet, then there is a traced version on parchment paper and then the final result stamped in red on a post-it note

I have an image of a convertible 1969 Camaro, but it has a bit too many details. I'll have to simplify it quite a lot before I can carve it out.
