This is an update to a previous review. Have 35,000 miles on the car and it is extremely reliable. Just installed the Bridgestone Serenity tires, and these are the perfect tires for the car. They take the edge off of the sports package ride without compromising handling, while providing more quiet operation, longer tread life, and all season capability. These tires really give the car a better ride that is more fitting of a luxury car. Have also used Dunlop SP SportMaxx tires which handle well and are quiet, but ride stiffer, have shorter tread life and are not all season. Continentals that come with the car are just o.k.
Logic 7, quiet ride, power, handling, auto sunshades, iDrive, controls, cabin storage, and reliability.
Easier to use navigation. Allow iPod software to work with cars equipped with rear entertainment system (as mine is equipped).
