Before you buy anything, get over to a gathering of Cobra types and take a look at all the different cars; chat up everyone; ask for a ride.
You'll probably find more similarities than differences between all of 'em, although no two will be exactly the same. Buy what feels right and appeals to you, regardless of the make.
However, do not buy one of these things, Shelby or otherwise, with the idea that you can make money on it. You spend money on Cobras...the cash flow only goes in one direction...but it's worth it.
