Checking out a 2012 MB GL-450 with just over 110,000 miles on the clock. Interior is leather, there is not a scratch on the interior or the exterior. The doors feel like the proverbial bank vault when opening and closing. According to CARFAX, all maintenance was performed by the dealer. They are asking 17K.

Fuel mileage is around 16 in the city, 20 on the highway. I'm concerned about ongoing maintenance costs........your ideas and input are appreciated!
