A low price isn’t a bargain if it creates rework on a Maybach windshield replacement. Use a red-flag checklist before you schedule. The biggest warning sign is anyone who says calibration isn’t needed without verifying your Maybach VIN, trim, and ADAS equipment. Reputable shops explain whether pre-scan and post-scan diagnostics are performed and itemize static or dynamic calibration when required. Next, challenge vague paperwork. If an estimate won’t specify glass type (OEM vs OEE vs aftermarket), won’t list part numbers, or omits moldings, clips, and one-time-use fasteners, expect fitment problems and surprise charges. Also avoid cure-time shortcuts. Claims that you can drive immediately or that SDAT doesn’t matter ignore adhesive safety requirements and can compromise occupant protection. Warranty reluctance is another signal: if the provider won’t put leak, wind noise, and workmanship coverage in writing, you’ll have little leverage if problems appear. Operational issues matter too—no clear address, no proof of business insurance, unclear technician training, and no explanation of pinchweld protection or corrosion treatment. Finally, watch for bait-and-switch pricing: quoting OEM but installing another category, adding unexpected mobile fees, or pushing cash-only payment. In {city}, {state}, Bang AutoGlass provides itemized estimates, clear calibration guidance, and SDAT you can trust.
