Terrible..... I was told that my extended oil changes that I payed $600 for will end in 2021 or 55k miles ,when i got there the service adviser told me the only thing I have left is tiers rotation and I have to pay for my oil change ,I had only 3 oil changes on my extended service that I paid $600 , its a scam and if u buy a car from this dealer don't buy any extended warranty because they will get you somehow...would I go there again never, and I will make sure not to refer people to this place....
