I own a 1985 911 and a 1986 El Camino with a combined 552,000 miles. I can go to the garage at any time and tinker and find something to fix or work on. Recently the lever for the turn signals on the Elky broke at the switch.
That one lever is a Rube Goldberg contraption that controls the turn signals, high beam-low beam, cruise control, and the windshield wipers. All separate switches and controls cobbled together.
There is a weird spring that has to be in just the right position to get the ignition key lock back in place. It only took me a couple of days to do it all, but I am the slowest mechanic around. And finding a pro mechanic to do it is pretty much impossible. No one works on 80s GM cars anymore.
I have had the range of typical household things to fix. One of my wife's friends is a widow. She laments not having a husband around to fix little things. I suggested she do it herself, men don't have some innate knowledge, we just dive in, and figure it out.
