What do you guys do when your service advisor does a nice job when you take your car in, but the mechanics in the back royally screw up? I hate to give low marks because it seems like it's going to fall squarely on my S.A.'s shoulders, even though it's not his fault. And if I don't give low marks the BMWNA thinks everything is hunkey dorey at that dealer. I always recommend that they change the survey to reflect the S.A.'s performance, and the mechanic's performance. Anyone else have this dilemma?
