I do give 10's where earned, but perfection has to be earned. I give my dealer a lot of 9's and 10's on all the social aspects.
I've only had one 7 experience with this dealer: Tech and service writer half assed an honest question about rough idle and gave me a laundry list of things (obviously without looking--like clean throttle body when it's spotless from a catch can) or pay for spark plug replacement 10K miles early--I knew they didn't scope it with that one or they'd have told me which cylinder was acting up.
So I gave them a seven and explained in my comments that they half-assed it. That was a Saturday and the regular service writer would never have blown smoke at me like that.
And, before someone defends them, I ran a can of Seafoam through the induction system and the rough idle went away--these sloths could have tried to sell a BG induction cleaning and I'd have had more respect, but instead they just blew me off.
Maybe the service manager appreciated my explanation for the 7 as a "teachable moment."

Its a shame because this is the type of behavior that gives mechanics and dealer service a bad reputation. Seems like it happens a lot to women and the non-mechanical.
