Automotive mirrors are the most replaced part of a four wheeler. Generally the entire mirror assembly does not need to be changed, it is just the mirror that gets damaged and needs to be replaced. Many people opt for replacement auto mirror instead for going for the ones available at the dealers. This is a good decision as the factory mirror from the auto manufacturer cost a lot of money. Especially if it is from a luxury car manufacturer like BMW or Lexus etc, the cost is prohibitively high. This is why one can consider going for side view mirrors from other companies.
