I Am a Master Technician so I do it all
I'm in the middle of stripping her down to re-paint
Before I paint I'll pull the motor & overhaul with a cam, Intake, headers, (sidepipes??) and clutch and...and...and...
I try to do as much myself as possible....I dont like the idea of my car being at a a shop that doesnt love the car like me....Its real easy to chip a door on a lift or jack up a c-4 in the wrong spot! I will admit that sometimes I have no choice & have to bring the car somewhere to be repaired but I dont like it!
I do my own stuff except the things that take special machines ie alignments, tire mounting and balancing. My brother-in-law has access to a tire changer but it won't do aluminum wheels so I have to pay someone else to do it. I always take the wheels and tires to them instead of leaving the car with them.
