I like the sepia but agree that B&W could look good too. I looked at your flickr stream. The photo closest to what I'd want is:

That photo is an example of how I would have framed it, BUT, to me it's going to look better with a wider lens from a closer distance because the car will fill the frame even more. The car is not in your face enough. A wider lens from a closer distance, will make that photo. Shallow DOF focused on the Ford and license plate should work.
Kit lens, 18mm, f/3.5 and get closer!
PS - nice photos on flickr; I liked looking at them.
