The first response got it right, join a local club. Attend some meetings, and get to know the guys. Why? First, you will gain a lot of model A knowledge, and get exposed to a variety of cars and styles. If you are nice, they might even let you drive one or two of them. Next, you might find the car of your dreams right there in the club, with a for sale sign on it, or get a good lead on one. Lastly and most importantly, you will make some great friends, many willing to give advice or a helping hand when you do get your dream model A and need help getting aquointed with her.
That Random Rog guy, he got it right in post #2, so now I guess he is "Always Right Random Rog". If you are near SW Washington, I highly recommend the Volcano As club. Check out the website, and come join use this Monday at the annual Christmas party. You won't find nicer people (except for this one *******, thats me).
