I'm kind of caught in the middle since I've already had my car for 4 years and 40k miles. I was going to supercharge, but I honestly don't think that will satisfy my thirst for something "new".
If my car was 2 years old or so, I'd be all over it, keep it for another 3-4 years then move to whatever is out or coming out then.
