Once you’ve got the keys in your hand to test drive the model you’re considering, don’t plan to set off right away. Though this generation E-Class looks to be fairly solid where electronics are concerned, as a German car, it should be inspected for electronics issues with a fine-tooth comb.

Plan to spend 20 minutes going through all electronics-related gadgets. Use each and every feature inside the vehicle that runs on electricity, including the windows, power tailgate (on wagons), climate controls, seats (including heat and ventilation functions) and the like. Ensure proper operation from the navigation system, COMAND interface, Bluetooth, audio system and all safety systems. Once you’ve completed checking everything over, check everything over again.
Look through the driver computer system for signs of any warning messages that could indicate a problem. Any messages that contain words like “MALFUNCTION”, “FAILURE”, “INOPERATIVE” or “SERVICE REQUIRED” or “LMFAO $$$$$” should be addressed ahead of your purchase.
Note that in many cars like the E-Class, niggling electronics issues like these can be caused by a weak battery, which often results from infrequent, low-mileage drives that don’t allow full recharging. If these sound like your driving habits, invest in a battery tender and plug your E-Class in to it when it’s parked.
Avoid models with the AIRMATIC air-adjustable suspension to avoid pricey repairs down the line. As a general rule, suspension systems are more durable when they’re made of steel and iron, not airbags. Having done hundreds of used car investigations, I’ve never come across an air suspension system I’d recommend.
Finally, this generation E-Class may have been modified by a previous seller. Wheels, tires and suspension lowering are among the most common modifications, especially if the vehicle was once owned by an aspiring rap artist.
In fact, there’s a computer programmer that allows the air suspension to be set to a lower ride height than programmed at the factory. Avoid a model that’s had this modification. Note that in some cases, lowered suspension can cause adverse suspension wear and other issues. Stick with a model that’s factory stock to be on the safe side.
If the unit you’re considering has non-factory wheels, be sure they are of high-quality – and not Chinese-made eBay ‘DUBS’ knockoffs.
The Verdict: Though information is somewhat scarce, this generation E-Class appears to be a fairly solid luxury car buy – especially by comparison to the earlier versions of the last-generation E-Class. The fact that Mercedes recognized these reliability and durability issues and worked on the W212 E-Class generation to remedy them is another good sign of confidence.
Opting for a Certified Pre-Owned model that’s familiar to its selling dealership is your best bet for peace of mind. If shopping privately, do not agree to finalize your purchase until the model has been inspected by a Mercedes mechanic, had its service records verified, and had a computer system scan performed. To avoid high repair bills for the long term, an extended warranty is a good idea here, too. A V6-powered gas or diesel model should be the least expensive to run and insure.
