C-Class tells the typical tale of a used German premium car
Owners commenting online tend to rate the C-Class's comfort and styling the most highly, with driving dynamics and performance following closely behind. Most report satisfaction with the way the car cruises, even at higher-than-advisable speeds.
The upgraded Harmon Kardon stereo system is a real hit with audiophiles, though some report dissatisfaction with the placement of certain controls within the cabin.

On a test drive, ensure all of these controls and their associated functions are working properly. The vast majority of owner complaints detail fussy electrical problems ranging from annoying cluster lights, random 'check engine' codes and the failure of various accessories including the keyless remote and heated seats. The stability control system can act up as well, even putting the vehicle into a crippling 'limp mode'.

German automakers aren't known to be the world's best electricians. Thus, given the often frustrating and sporadic nature of electrical glitches, it's advisable to uncover any potential issues on a test drive. If any are apparent, you'd best be looking elsewhere.

Look for a C-Class with a full service history where possible. Most C-Class drivers would agree that the pros outweigh the cons in terms of driving dynamics and style, though those frustrated by moody electronics would happily disagree.

Note the condition of the vehicle's interior, too. Mercedes-Benz products aren't exempt from the wear and tear that plague anything else on the road, so the shape of the leather seats, carpeting and interior trim should be noted.

Knocking noises from the front suspension could be worn out bushings or ball joints, while tapping or scraping noises from under the centre of the car could be caused by drooping transmission insulation touching the driveshaft. Also, be sure to note any questionable ticking sounds at startup in the four cylinder supercharged engine, as well as any hesitation or fluctuations in idle speed from the V6. Either sign could indicate a problem dealing with cam adjusters or sensors, respectively.

Recalls dealt with a possibly faulty computer calibration that could affect the fuel system and speedometer, a faulty steering shaft nut, potentially defective seatbelt latches and the possibility of a hydraulic leak on to the catalytic converter. Your dealership should be able to advise you if any recall work is outstanding if you provide them with the vehicle's VIN number.

In all, the C-Class's story is one typical of many German premium machines: great to drive, but potentially fussy to diagnose and fix properly. Protect yourself during the buying experience with an extended warranty where possible- or look for a comparable Japanese product instead. They are known to have the world's most reliable electronics, after all.
