Thing that the 5 series is a bit scarce on the rear leg room? Well, the brand came up with a solution (no, not 7 series, you dumbo!). The 5 series Gran Turismo is a lot of 7 series that has a rear spoiler and raised suspension. This model came standard with the 3L inline six diesel motor that is frugal on your long highway runs and does not put on hole in your pocket while commuting around city. Made for people who like to do expressway travel but don't want an SUV.
