You are alone on a Tuesday night on a north Georgia country road, the CPS conks and you have a shiny new Bosch sensor but no tools.
Even AAA don't carry a E10 Torx socket, and that chicken farmer that stops to help ain't gonna have one either. Autozone, Advance and O'Reilly are long ago closed up.
AAA says "Sure we can tow ya, but only by a front lift, you'll have to wait until tomorrow for a flat-bed, meanwhile you can leave it here on the side of the road as a big fat target for empty Miller Light bottles while I drop you off at a motel".

So, who you gonna call ?
Me ?
