I'm already began to look for ways of how I could customize the appearance of a Buick Verano IF I were to buy one and I wanted to know if the Verano's rearview mirror housings are shared with any other GM production car specifically the Regal? If the mirrors are indeed the same on both the Regal and Verano one of the first things I plan to do is swap-out the Verano's for the Regal's rearview mirrors that have the turn signals embedded in them.
