Super reliable except airmatic suspension.
2011 Mercedes-Benz GL-Class GL 450
Rides and handles like a dream. Love the rain sensors and other conveniences. However, be prepared that sometime after 80,000 miles, you will have to replace all four of the airmatic shocks, and, likely, everything else in the airmatic suspension. It is really the one thing about this car that I find unacceptable, since changing out all of that has run over $4900. And that is at a repair shop... Think double that for a Mercedes dealer. Other than that, the vehicle has been extremely reliable. Even with the suspension issue, I'd likely still buy another.
