Something else I've often considered drawing... a classic car. So I finally found one, a '58 Buick Limited.
For anything else you'd like to know about this car, and more pictures of it go here: www.ev1.pair.com/buick/buick_1…
I simply added some contrast and changed a few details (especially the background, lol).
Edit - Updated with a better file (and watermark now, sorry) and it is now available as a print.
