It is an assembly line left-over, pulled straight from the GM box. It is in excellent condition. Why pay the same amount or more for one that's been taken off a wrecked vehicle? Or one that doesn't include the cover. Match your part number or you risk it not matching your color. We are not guaranteeing a color match. We are selling it to FIT and FUNCTION on the vehicles listed. If you end up with a color mis-match as a result of a different part number, plan on having it painted. Either way, new mirrors are hard to find for this vehicle at this price. APPLICATIONS Cadillac CT6: 2016-2018 (with matching part number) SHIPPING INFO Shipping cost is based on weight and zip code.
