Again... I know what you're talking about. If you're worth $100/hr and time=money then spending your time fixing your cars costs money.
This is why people perfectly capable of doing things choose to pay for it.... like home cleaning or landscaping etc. If I'm working my ass of in the office all week I'd rather spend the weekend driving my Porsche to the golf course and then to dinner etc. vs. cutting the grass, mulching, weeding, and doing a brake job on the car.
Again... I never said the service industry didn't have a place in society... obviously they do. Just... at a very simple basic level, could a dealer increase revenue by modifying pricing/policies on customer pay operations.
That's all
