Not rushing the decision is good advice. I always wanted a "Cobra", and once I figured out I really wanted to buy one I spent about 4 years looking at options. It came down to an SPF or SA built CSX. I thought alot about what I wanted out of the car, and how I wanted it set-up, and the SPF was the best choice for me.
I have had the car going on 5 years now, and I don't regret the purchase at all. This is the only "toy" I have owned that never gets old. Take your time, do your homework and look at different brands. If you rush into it and just buy the first car you look at you might regret it. Different people want different things from these cars. Find out what car is best for you.
You might find out that a Vette is the best choice.
