I attended the DC auto show which started Janurary 28th 2011 and runs up till February 6th 2011. Tickets are just $12 for an adult so if anyone is in the area, you should definitely have a go.
I did not get to cover the whole area as it would take too long and with the amount of uncooperative people around it was very difficult to take any acceptable photographs.
The photos are posted in no particular order.
Anyway here are the pictures. Enjoy.
