A middling buy. Check the air suspension, steering and M276 oil pressure first, since air suspension faults are the biggest risk.

Air suspension: a sag after parking or a "vehicle too low" warning points to a fault. A scanner reads it and runs a leak test. Bad result: two air springs or a compressor.
M271: start cold and listen for clicks. Ask whether the chain was replaced.
On a lift, check sills, arches, lower door edges, tailgate and jacking points for bubbling or holed metal, or signs of crash repair.
Turn the wheel lock to lock. Bad result: whine, rack knock or fluid under the steering gear.
On a lift, check ball joints and bushes for play, leaks or knocks.
Check coolant level and temperature on a warm drive. Bad result: low coolant, overheating, or a noisy pump.
Check the sunroof drains are clear, then test the boot release, rear lamps and reversing camera. A scanner reads data-network (CAN) faults.
Test keyless opening from each door and the boot, then check the battery after the car has stood. A scanner reads antenna code 889, according to Kfz-Meisterbetrieb Dietrich.
