AutoNation Buick GMC West

I have a Saturn ION. Saturn, used to be under GMC, but is now defunct. Saturn uses GMC parts so I need to take it to a GMC dealership. My car is over 100K in mileage; I happen to acquire the original Saturn "Maintenance Log: High Altitude Service Requirements" as a hard copy. I prefer that they take their time to do the maintenance right so I tend to schedule in the middle of the week and leave it over night. In general, service advisors always seem to ask: "What is needed ?", to which I reply "do what's in the maintenance book for the mileage". I tend to forget what was previously done and when (for example: "flushing the transmission fluid"; I hope their computers logs will be able to answer for me Typically the AutoNation website "schedule Service" feature does NOT allow a text area field to accept your input on what you need. (It still does not) This time I was **PLEASANTLY** surprised by #1: when I scheduled service, I got the email address of my service advisor allowing me to send email with a PDF file attachment of the relevant page in the previously mentioned Maintenance log #2: the service advisor was able to consult their "maintenance computer" on suggested maintenance line-items and essentially ONE UP ME (or do it better) #3: the service advisor left a voicemail indicating: "it was done and ready for pick up" (typically they tend to forget this step. I call ahead to make sure before pickup) The first wrinkle (which that Autonation has NO control over) was due to a personnel shortage, I had to wait an extra day for the maintenance to be completed The only other wrinkle was that when I dropped off my car in the afternoon (the day before the appointment) ... the courtesy shuttle was unavailable (assigned to pickup parts) so I had to take a cab home. It took the cab company roughly an hour to dispatch a taxi (luckily I cleared my scheduled and assumed the worst case)
