Rakan0 5pts The argument about the economy and the economic sense goes for all luxury vehicles and items for that matter. But, how the car drives, handles, feels, and how it compares with competitionetc. As an owner for GL 450, the car is as luxury as it intended to be except when it comes to costly maintenance and parts. The new upgrade is following the new trend from all manufacturers, just a refinement/improvement on the previous design, where you can see the ghost of its predecessor, it isn't really a complete make-over. But I think it's a beautiful refinement and I hope the endurance, durability & quality been boost up along with BiTurbo to reduce maintenance cost and to make it more viable.
