Seems like with glass replacement, the options for the actual glass may include one or more of:
- OEM glass
- Aftermarket glass from the OEM supplier (Saint Gobain Sekurit in the case of Tesla Model 3 windshields)
- Other aftermarket glass
While labor can be at:
- Manufacturer-affiliated shop (Tesla service center for Teslas, dealer for other brands) -- may subcontract with other glass repair shops
- Chain / franchise shops (Safelite, AutoGlassNow, etc.)
- Small local shops
Either the glass itself or the labor can be significant in terms of the end quality of the job. For the glass itself, it is probably safest to stay with either the OEM or aftermarket from the OEM supplier, rather than other aftermarket. But labor quality can be luck of the draw at any of the different kinds of shops.
