Lots of great points and that's exactly what I struggle with. I'm only 35 so the working part doesnt bother me but the price end is very tricky. I'd like to work on nice cars for many reasons some of which include the "no hassle" in getting permission to repair what is wrong, cars are clean and well kept and are normally only weekend cars so I can take my time. That being said, I am sort of out of the city so people normally have a good drive to drop their vehicles off. I want to charge a fair price but it's not like I have a 12k/month mortgage and I also believe that when you charge too much people have unreal expectations. I current have a Dodge Viper on my rack, getting all the fluids changed, spark plugs, fuel filter etc. During the drop-off the owner saw mine which is lowered, so then we added that to the bill for his car. The next day I found the sway bar links were toast, output shaft seal leaking, doors needed realigned and hood needed ajusted and it was no big deal to him even though I was going to have it for longer and the cost had trippled.
