I would like to provide some input for prospective purchasers of the OM642-engined S204/W204.
Favourable:
Approaches the intermediate speed of a '55' AMG, sufficiently rapid for road use and enjoyable.
Pleasant resonance from the subdued V6 engine. Not silent, but in comparison to the canal boat ambiance of the four-cylinder Mercedes engine, this was akin to the Silver Ghost standard.
Exceptional chassis dynamics, navigates corners akin to a 3 Series.
Favourable fuel efficiency for extended journeys at or below 70 mph, namely 38-40 mpg contingent on conditions (but consistently at least 10% more optimistic than the displayed readout).
Mine had approximately 120,000 miles and was dependable during the 20,000 miles I owned it.
Attractive vehicle despite its age.
Compact dimensions, practical for transporting loads, yet easy to manoeuvre in parking situations.
A 12-year-old Mercedes devoid of corrosion is remarkable!
It was nearly ideal for my needs, except for the steering.
For prospective purchasers: ensure that it does not have a persistent tendency to veer left consistently.
Unsatisfactory:
Severe design defect related to steering, which prompted my decision to sell it. It exhibited significant sensitivity to road camber. It veered left predominantly because to the leftward camber of the roadway, namely on the left side of the road crown. Consequently, while on holiday overseas, it veered to the right when driving on the right side of the road. On level ground, it did not exhibit pulling; hence, I do not consider this to be an alignment issue. I am not referring to a standard moderate drift; rather, this was an immediate and persistent pull to the left (or right when driving on the right). It infuriated me.
Note Kindly refrain from directing me to the WheelsInMotion sticky topic. With with respect, it is illogical to adjust caster and camber to prevent a Mercedes from veering left, only to induce a rightward pull on level surfaces or during international driving. Particularly since the majority of vehicles do not require this 'oval racing' type of asymmetrical configuration. Furthermore, I had the wheel alignment performed at Micheldelver Protyre, which resulted in minimal improvement. Furthermore, I currently possess a BMW that consistently maintains a straight trajectory, regardless of the road's camber.
Research indicates that this issue only affects W204 models from around 2012, while other models remain unaffected. Strange and bothersome (at least from my perspective - many on this site disagree). Had the alignment assessed at Micheldelver Protyre, who, after charging over £300 and adjusting the caster/camber to create a staggered configuration, stated, “all resolved now, sir.” I observed that it remained unfixed within a distance of 200 feet. I returned and remarked, “Excuse me, this is scarcely different from when I submitted it,” to which the mechanic replied, “They are all similar; very difficult to repair.” That information would have been more appropriately conveyed prior to the expenditure of over 300 pounds.
Additionally, other minor grievances:
Annoying little rattles and squeaks. I addressed most issues by the judicious application of anti-squeak tape and wedges, but the primary source of the buzzing sound was the seatbelt tensioner, which I remedied by inserting sponges beneath the trim. In my opinion, it is inappropriate to be making these repairs on a luxury vehicle.
The dashboard gauges: Lexus gauges exemplify the ideal appearance for Mercedes gauges. In contrast, contemporary Mercedes vehicles appear as though the dials were conceived by Amstrad, characterised by geometric lines and excessive intricacy, lacking clarity and sophistication.
My 40-mile round trip to the office during winter yielded 34 miles per gallon when driving with utmost caution, and perhaps 36-38 miles per gallon on extended journeys. The performance was satisfactory, but it warrants attention.
Severe suspension and low-profile tires. It was aesthetically pleasing; nevertheless, on southern highways characterised by poor surfaces composed of small stones rather than gravel, it frequently proved uncomfortable and noisy. Indeed, I believe that tyre noise was a factor that detracted from its performance.
The seats were neither uncomfortable nor exceptionally comfortable.
The central dash illumination activated only at a certain period, rather than in conjunction with the headlights. If the day was overcast and the headlights were activated, the central dashboard would remain unilluminated. Unusual design defect.
It is evident that, had it not been for the peculiar steering, this would have been a valuable acquisition. That is just unfortunate.
