Our 2001 CLK430 was in the MB shop and now we are told we need 3 new AMG wheels due to cracks (they seem to indicate it was caused by impact)...Baby got new tires in October - no mention of any issues then. Now 5 months later - we lose 3 wheels - it just doesn't seem to pass the smell test. Anyone else have issues with AMG wheels. As an alloy wheel - are they too brittle? Help please with any advise or technical knowledge - thanks
