What is best and least expensive way to replace bumper. Got estimate of $857.48.
This is a scratch on the passenger side from parking in a rocky parking lot. Bodyshop
Said whole bumper needs replacement. Googling on line to see if I can just order the
Bumper brand new in silver and have a mechanic put it on?? What is the best way to
Go as I have little if no experience with cars. Thanks!!

You can try checking at local junkyards and hope to find a silver accord that was severely rearended and still has a nice front bumber:)

OR... you could buy a bra and cover it up!
