BMW 550i Gran Turismo: An Owner's Review of 4+ Years - BMW BLOG (blog)

The 5 Series Gran Turismo’s best feature is its interior and cargo versatility. My 550i GT came equipped with 4-zone air conditioning and heated seats in both the front and rear. So every passenger has ample leg room and the ability to control their own comfort settings. The rear seats are manually adjustable, but this feature hasn’t gotten any use really. The parcel shelf or trunk cover, as BMW calls it, is easily removed and stowed in a compartment under the trunk floor. There is a partition between the rear seats and trunk area, sometimes just releasing the partition and gaining a few extra inches has made just enough space to avoid folding the rear seats down. I’ve put quite a lot of cargo in this car, with the partition and adjustable rear passenger seats the cargo carrying capabilities in the 550i GT are almost endlessly customizable. And having a coupe-like roofline has never been an issue, I’ve had furniture, trees, luggage and moving boxes in my 5GT. My only dislike is the air diffuser that deploys when you open the panoramic sunroof. The majority of its surface area is made up of a mesh material, at speed the wind buffeting is annoying, though it can be cured by either opening one rear window just two to three inches or opening the windows to whatever level you’d like.
