I saw a black Audi A1 on Thursday when I was driving to work. It was on the Roosevelt bridge heading into DC. It was night, but I became curious when I saw the silver roof rails and the unfamiliar taillights. I was able to get close enough to confirm it was an A1.

The A1 is not sold in the US, but this car had a Michigan manufacturer's license plate. Volkswagen of America's headquarters is located not far away in Herndon, Virginia, so that might be related.
