Ooh, those are good. I have a few homemade (or home-modified) specialty tools for my old cars, and some I'll certainly never have use for again.

Those are one reason I've never yet had a British or German car, though I do have one with a British-derived engine and a German fuel injection system. (I'll have to remember to pass on all the custom tools when I get rid of the car. The chances are slim to none that I'll ever own another one.)
