To be exact, 3
7 miles if that makes it any easier to swallow
Seriously, I debated until the last hour of my confirmation week. I justified the 90D after test driving an X
P90D in 90D mode. I didn't want to regret the acceleration loss, but maybe no biggie for some. Also, I thought I didn't need the Air Suspension, but then thought how nice to have for snow on untreated driveways and maybe other similar road clearance situations. The ability to tow an actual trailer if needed for dirty yard stuff et all was the final selling point for Air Susp, and after that only 13K more for range and speed better then any car I have ever owned.
