2 not 1 but twice different weeks/months tried to walk in and get an Oil Change! Little nothing Oil Change! 1st month Lady Service Rep… Said "No we can't get you in! Must make an appt! We can't do walk-ins…" I said "For an Oil Change?" She said "No!" What the Hell! Huge Dealership and Service Center can't take a walk in on an Oil Change!!! Horrible! Month later walked in different time and day… Same thing, old man said "Hold on", he went and asked Service Manager or Assistant and He said "Gotta make an Appointment." Whatever excuse! Worst Chevy Service ever I came across in 27 years! If Owner only knew how much business walked from these actions! Word of mouth travels miles! Absolutely Horrible! Place gets 0. ZERO Stars!!!
