One of my ski buds inherited an early 2000s ML, and he's had lots of issues with it, recently replaced with a Pilot, but the old ML, when running, drives very nice, the interior is like new and if it didn't have so damned many issues, would be a great daily driver.
(Please send me my run-on sentence trophy immediately...)
No doubt Mercedes can make a very nice vehicle, and if you get a reliable one, can be super enjoyable.
