2013 GL350 - Still running strong. No complaints, 0.5 quart between 5k mile oil changes, 24.6 average MPG, cold A/C, rides GREAT. It does help to be a DIY’r and a gear-nerd to own one. My #1 suggestion is to fix issues that pop up immediately don’t kick the can. You can foul up some expensive stuff kicking the can down the road.
