As a followup to my question I have found a few top notch facilities over
the past year.911 Enterprises(Randy),Loudens Autohaus,Ewing
Autohaus,Autoscope,Lazlo's,Dallas Autosports,and Dalas Roadster.All were
very helpful and knowledgeable about Mercedes.The problem is that they are
specialized and therefore can charge almost as much as dealer labor
rates.Since Ewing Autohaus stands behind their work,I tend to keep going
back to them for any work.I will continue updates as I find new places.
