Auto window tinting is not always "standard" on vehicles sold through a dealership. In fact, of the methods available to tint auto glass, two occur after you have already bought a vehicle from the dealership. Here are the three ways you can get tinting on your window glass in your vehicle if you decide that you really want and need window tinting.
Auto glass manufacturers apply coatings to glass that are then tempered and sealed. The tinting cannot be scraped off or removed in any way when the glass is tinted in the production plant. It will stay on/in the glass forever, and you can only request this glass in a few ways. One, you only buy a car that already has this glass installed. Two, you request that a dealership order a vehicle for you with the tinted glass as a custom order. Finally, three, you ask that a vehicle you want to purchase be sent back to the factory to have the addition of the window tinting added there and then be shipped back to you.
Through an Auto Glass Shop
An auto glass shop can help you with window tinting as well. Usually what the shop does is apply a coat or two of tinting to the glass for you. Because it takes time for the technicians to remove the windows from your vehicle, lay the windows flat, spray on the coating, wait for it to dry, spray successive coats and wait for those coats to dry, and finally reinstall the windows, you will need to leave your vehicle with the glass shop for a few days. The glass shop can also order tinted windows and have them installed on your vehicle in place of the windows you already have, but then you have extra windows that you do not know what to do with.
Applied via Stick-on Vinyl
If you want to remove the tinting from your windows at any time, the above options are going to be difficult, if not impossible, to remove. If you would like to just try out tinted windows, you can buy stick-on vinyl clings that tint your windows without sprays or long wait times. You can even apply these stick-on "tints" yourself, but you have to be careful not to create any air bubbles in the application, or it will make your car windows look very weird.
