I think it was in the seventies, when the goverment was putting pressure on the car companies for emissions, fuel mileage, safety and other things that would require complex technologies that in response Lee Iacocca said something like "We might as well weld the hood closed on these cars because no one going to be able to work on them in their driveway" At a dealer "open house for it's wholesale parts accounts" i went to about ten years ago i was talking off the record with a factory rep. The "open house" was really a head count of to see who that dealers service competition was. The rep went on to talk about cars that would e-mail dealers/owners about needed car repairs/services and incorrect repair procedures being done by others,etc. He even talked about cars now on the road in Detroit that someday will drive themselves to the dealer for service. Even if we get the Right to repair i feel that we may be running out of customers (middle class) that can afford the repairs and $100.00 plus and hour plus crazy electronic parts prices. I am seeing more a more car's with check engine lights,,abs lights,srs lights on that the customer does not "care about" due to the expense. That being said as part of my full service i do what ever it takes to get the car fixed even if i have to drop off/pick up the car at the dealer. I get referrals from happy customers and dealer service advisors because they know i will get the job done.
