Every time I schedule an appointment for a simple oil change it takes at least 2 hrs . I m not understanding the reason for an appointment if it will take so long. And then when you ask how long they tell you a hour. If you go somewhere like precision tune auto, I m in and out in 30 mins or less and it s not as big as a dealership. The only reason I came back this time was to use my voucher. This is ridiculous and this is the second time I ve had to wait 2 hrs for an oil change.
