Slightly off topic, but the Audi dealership in metro Detroit (Bill Cook Audi) was hard to deal with. I guess one look at me, they realized I probably won't be upgrading to a $50k next from them (which is true). Even under warranty repair (coilpack, camshaft, autoclimate control sensor), I have to fight tooth and nail to get a loaner. That's right, a loaner from Enterprise.
The Acura dealership we didn't buy the car from was actually much nicer than the one we bought ours from. The one we actually bought from, from warranty work to services, refuses to give us any type of loaner, even if we call early (Acura of Troy). Acura in Farmington Hills was very nice and courteous each time. Loaner. No problem. Happy to oblige.
Since then I do all maintenance work on my own. Haven't step foot in the service area for almost 7 years now. Don't intend to with the CX-9 unless it is warranty related.
