I am new here, as I'm looking for a C63. I found a 2009 that I like, but has the old head bolts. Has anyone here had luck with any indy shop in the Chicago area replacing the bolts? Any estimates on cost? The dealer where I was shopping for the car quoted $8k. I've seen estimates of $2k on this forum, but was unable to find anything specific to my area. I appreciate the help.
