kaptekarv,
Welcome to your new addiction. There is more information than can be put on one post.
I would first recommend deciding what you intend to use the car for. Will it be street only? Will you race it? Is originality important to you? Decide what is most important to you first.
Then read, read, read. You will find lots of information on all kinds of Cobras here at ClubCobra. Everyone is very helpful and will tell you anything you want to know.
The budget you are looking at will likely limit you to a basic level car, likely Factory Five. I have an FFR, and love the car. If you want specific FFR info, you may also wish to visit
www.ffcobra.com, which is a forum for FFR owners. But you will find great info here, with opinions from all sides, which has tremendous value.
Best of luck in your search.
Steve
