Gerber fixed the back skin of the bumper on my car over 1.5 years ago and the work was great- bumper looked like new. Went back because one side was slightly off complete flush just to ask if I should worry about it and and Bill the general manager said I should get it adjusted and he insisted he do it right then on the spot for no charge. He got it fixed in 10 minutes and I was on my way. And this was on a Friday at 3 pm as I just happened to be driving by.
More than i would ever expect as it could have been a recent car wash that caused the slight misalignment. They really do stand by their work and treat you right. My highest recommendation and I would never bring my car anywhere else to be worked on.
