This is all well and good, but there is a point (don't ask me what that is) where you're cutting your own throat. Some people simply cannot afford repairs as today's prices. You turn away business from people who may need it the most. People who may not be physically able to do the work, or do not have the tools, equipment or know-how. This is in part why there are so many junk, less than safe cars on the road.
I don't know what the answer is, but I know things cannot continue the way they are. Some people may literally become housebound because they can't afford repairs and they can't afford new, and in rural areas, there are few, if any options for transportation. We have one that covers a few counties, but their rates are over a dollar a mile and they need to be booked several days ahead of time.
