Terrible – Extremely expensive, not worth the grief of the unbearable road noise after 25,000Klms. Complaints to MB fell on deaf ears. They still think I was complaining about the low Klms, not so. My complaint was about the unbearable road noise. Next time, I'll buy a car whose manufacturer actually cares what its clients are saying. I'm off to replace the tyres, and it wont be with Pirelli. Great when new, good grip and reasonably quiet After 25,000 Klms, unbearable road noise. Fitted on to a new E280CDI.
