No one has even touched on the vastly improved handling dynamics. Those front wheels do a marvelous job of pulling you through corners. They also pull you down the highway so you can run very little toe in the rear yet have excellent straight line stability.
Do be warned..... You will be disappointed with daily range. I ended up turning off my trips on my dash so I did not have to look at it. The up side is I am having a lot more fun with the car
Oh, and those seats are worth it all by themselves.
