Old timey concept cars

I've posted about the Pontiac Stinger, perhaps the finest concept car that never quite made it into production. Of course there are a lot of other concept cars that also tragically never quite panned out. The examples in this post are from the early days of car design. Oh, what might have been.

There are more after the jump. I found them at the Today's Whisper web magazine post Creative cars of the past, where you can see many more examples.
