I got a recommendation from the Dallas MB dealer a few years back; but can't remember now which company it was. The tech came to my house. Unfortunately he didn't know JACK about replacing my 126 windshield, and I had to advise him. He actually didn't even know that there are two tabs at the bottom that support and position the glass in the proper place.
I had assumed the worst, and had taped off everything, and removed the wipers, a-pillar trim, etc; ahead of time.
Together we did a great job.
I even went to the dealer and bought a new Daimler sticker.
