Well... as you know, the Sport is $19,500 (plus tax) more than the base model, and the additional $ buys 0-60 at 3.7 instead of 3.9, adjustable suspension, and a tire upgrade. Obviously if money were not an object or of the price were identical for the 2 models, everyone would get the Sport. However, I am wondering ... for those who consider $19,500 a lot of additional money to spend when the car is already very expensive, is the performance difference really something that makes it worthwhile to go out on a limb and pay the additional $. I read a review that hinted that the difference in performance (non-track conditions) was perhaps negligible, and 0.2 seconds is not all that much of a difference in time. Has anyone done a careful comparison? If so, could you really appreciate a speed/handling or other difference? Thanks.
