Hey, saw your post indicating that you were thinking of selling!
Took mine to the track this weekend-finally, wish I hadn't waited so long the car was a blast. Even the brakes after initially giving some vibration smoothed out and I was impressed how good the stock brakes were too.
I haven't looked at the resale values in some time and believe that our M Sports are pretty rare-but not sure how much can be expected. I haven't found anything else that I'd want more-what are you thinking?
