I had been looking at the 07's as they were Certified Pre Owned with an extra warranty. Shopping online and increased my distance to cover more then 100 miles I found a great deal on the 09. The interior difference is mostly with the lay out of the idrive and controls. They made it more user friendly and easier to use overall. Very easy to hook up my phone with the blue tooth as well. The ride is amazing, very smooth. I did not get the sport package, as it does go through tires quicker, and the ride is still sporty, just a bit smoother. Love the parking assist as well. Basic stereo package could use more bass, overall I LOVE THIS CAR!
Navagation and idrive, parking sensors, CD player stores your music in the car like an ipod.
Tinted windows for rear, and basic stereo could use more bass.
