Hi Eric - welcome to the site! I am in the neighboring state of Delaware. I know Maryland is big, but I do get down to Cecil County Dragway and Maryland Int'l Raceway some times.
I suggest that you look over the forum and also the host site to check out the in-service pictures and learn about the different agencies. When I first started looking at SSP's in 2008 I didn't even know that many of them came with 5spd transmissions. But as you look around you will be able to decide on the things you like/dislike about certain agencies, which will allow you to be a more educated buyer. You will also need to determine a budget and how much work you want to do on a car. We constantly post up classified listings of different SSPs we find for sale. Be patient, and you will find one that suits your wants/needs.
