"Brought my Mercedes ML 550 in for a windshield replacement on full State Farm coverage The windshield has all the latest state of the art technology, recalibration needed etc and they did a perfect job. I have gone in the past to Westmont Mercedes to replace three, yes three windshields on this car. I used to have Allstate and they approved the dealer. State Farm would not. I was very hesitant because I felt only the dealer could do it correctly. Well, I was proven wrong. Auto Glass Masters got me in in one day. Took them 4 hours and I picked it up. Amazing. I give them the highest recommendation possible. Very professional and top notch. Benztek in Burr Ridge recommends and uses these guys. Enough said."
