On a new car, i generally live with it for a few thousand miles, work out any issues that may arise with my dealer, then i start modding. In all honesty - i like the car pretty much the way it is! If i could find & swing getting an SRT, there isn't much i'd do to it. If i get an R/T then my first mod will be wheels & tires (possibly swapping to SRT units) and a flash tune then take it from there.
