My experience with Duncan automotive was great from beginning to end. I had them do a smog check and oil change, which was very convenient as I needed both. The only issue I had was when I got the truck home and they had not wiped the excess oil off my skid plate. When I parked in the driveway at an angle, I came out to an oil stain on my driveway in the morning. It happened before after oil changes, but I will mention it next time to hopefully have them wipe the excess oil off and not have to deal with the oil stain.
