My buddy's trans am just sits in his garage, everytime he gets it out no one will race him or he breaks something... its a small town.
If it was my car, I would wait it out until you at least break it in over the summer. You have plenty of time to decide plus the car is pretty much new, you could put 8,000 miles on it and people would buy your parts for the money you want. I'd rather have a car that's not supposed to do something wicked than have a wicked car and make it faster. I think you'll have more thrills in the gp. Life sucks right now becuase its -10 out, don't punish the gp for it!
Either way its your decision, I think a turbo T/A would be badass but you already have a badass car.
