Can you find out the make and model or a car by the mirrors?

generally someone with an extremely trained eye should be able to tell the make and model by a side mirror, especially if the whole shell is included.

however, it may be a general make and chassis. for example, GM K trucks, which include Chevy Silverado, GMC Sierra, Chevy Tahoe, Chevy Suburban, Cadillac Escalade, GMC Yukon, etc, all use the same glass and similar shells.
