At most dealerships customers are banned from entering these shops already. Customers don’t really care where their vehicle is serviced.
I refuse to use a servicing dealer where I can't see in the service area or walk around the OUTSIDE to look in and watch from outside the doors.
Even though I have a Hyundai dealer 8 miles from me, I don't get service there because the car goes behind a door and you never see it again until ready. I use a dealer about 25 miles away. I can walk around the outside and look in the doors and watch.
My present Brand-X dealer is very close and I can see EVERYTHING from the open doors. If I have a question, the Tech invites me in and shows me. I like that.
In the last twenty years, I've cought dealers trying to cheat me had I not been watching.
Two examples.
1. Had a coupon for oil and filter change at Courtesy
Buick in Orlando. I had a
Buick. Was passing by and said"well what the heck" so I pulled in. Watched tech install a White filter. Told him that
Buick/AC Delco filters are Blue
Service writer would not do anything about it. Said "if I wanted a
Buick filter, I should have said something and it would cost me more". (Later saw it was a "Formula Seven" filter used by independent shops). A few years later, when I had a Chrysler convertible, I stopped into a new Courtesy Chrysler dealership that was still being built. Talked to a service writer. Told him what happened at Courtesy
Buick. He whispered to me, "we do the same thing".
Both dealers now out of business.
2. Went to a dealer and Brought My Own Full Synthetic Oil. Saw Tech put my oil aside and filled with a different oil. Tech said "oh, I forgot". Made them drain and put my oil in.
Had I not been watching, I would never have caught it.
Who knows what goes on behind those closed doors.
