Should you get it?
The real question is why do you want it.
If it's for the style and looks then there really isn't anything else out there like it.
If it's for the performance, you can spend less money and get something just as sporty off the track and in a lot of cases more fun to drive (all wheel drive Subaru WRX comes to mind). Straight line acceleration is fine, but having a lighter car with great handling and plenty of power will put more smiles per miles on your face.
If you are going to buy just to show off having one, then the odds are you will quickly tire of it and move on to something else once the "thrill" wears off.
It's your money and your life. Frankly if you have to ask "should I", then the odds are the answer is no in just about any situation.
