I bought my 2012 V6 Premium May 6 based on love at first site rather than sitting down and picking options. I had no idea what the car had on it other than what I could see as I looked at it and as I test drove it. Its AC wasn't automatic, it didn't have the electric passenger seat. OK. I could live with that. It did have 18-inch wheels which I really liked. They went really well with the black color of the car. Like I'LL TAKE IT AS IS! Because of my lack of checking out the options, I missed one option that I wished I had. That's the performance package, in particular the 3.31 rear. I would never have the 19-inch "summer only" wheels since I am not gonna be having to change tires every season. Now my question: 1) Could I have opted for the 3.31 rear only without the 19-inchers? 2) In normal driving, is there a noticeable difference in the car's spunk with the 3.31? Since I don't race, would it have been a wasted option for me? I'm not really having buyer's remorse 7 months after the fact. I am just wondering if I really missed out on anything super cool in my buying decision haste.
