Hi. I purchased my Ghibli in March 2020 from a dealer in St Louis MO. They performed a final oil change because it was a brand new vehicle, albeit two model years old. I have had no reason for any dealer servicing but visited the local (Grandville MI) dealer to chat about window tinting recommendations. I was impressed by the service manager. I will be visiting in March 2021 for my "first" scheduled oil change.
