You can't work on cars these days either.
My dad is selling most of his tools because most of them have become useless. I told him to hang on to them till next summer and we'll hit the classic car shows and we can find buyers who have use for them.
If he has old tools, sometimes those are collectors items in themselves.
Not so much call for kingpin reamers and the like nowadays, but the car shows are a good bet (or e-bay--good to check to get some idea what they are worth).
I have an assortment of oddball tools I picked up at the local Pawn shop and the occasional auction, and yes, because I have a couple of older vehicles, I can use them. I did avoid ones I couldn't use, though.
The newer vehicles go to my mechanic friend who puts them on the computer he has--quite the gadget, but more than I can afford for hobby wrenching. I have seen him use it to set timing and compensate for gear backlash in the distributor in a 200K old 5.7 liter vortec engine, and have it humming like new. That's neat, but it isn't like getting out the tach and dwell meter, timing light, and the vacuum gauge...or setting it by ear... The good ol' days, when being a good mechanic was as much an art as science.
