Craig,
Sit back, mix/pour/blend/brew your favorite beverage and read every post by LudicrousSpeed. The most documented research project in CC history, that almost ended in a car purchase.

Start from post 1 and you'll learn everything (and more) that you'll ever want to to know about SPF's and BDR's. I'm sure you'll probably read about some FFR cars along the way.
Best bet, connect with your local Cobra group and check out the cars in person. You'll figure out pretty quickly which car is right for you.
Next step is to beg, borrow, or bribe, your way into test driving a car. You're best bet, may be a friendly SPF dealer with a demo car or a pre-owned car for sale.
