Have purchased two vehicles through AutoNation Scion Tempe, and have always been treated great by Eddie and his great team down there. Scheduling appointments is extremely easy, and any issues that have arisen with my vehicle under warranty were always honored. In fact, when the throwout bearing (under powertrain warranty) went out on my car and resulted in significant smoke/burn damage to my clutch (manual transmission), AutoNation ensured that I would have a new clutch replaced on my vehicle as well. This was a class act on their part, and I respect the service reps at this location along with the management.
Will always use AutoNation, and I have had no significant issues with any appointments at this dealership. Would recommend to a friend, as I believe they are very trustworthy.
