Good point, Park Place does fix what they say they'll fix. Although, my sense is they also recommend fixing things that aren't in need of fixin'.
I've owned MBs for 14 years and worked with many dealers in IL. I never leave Park Place feeling good about the price compared to the work. It might be me, but the value equation is skewed.
