A mechanically inclined female who knows a lot about how cars work, but doesn't want to offend or piss-off her boyfriend who shows zero aptitude for automobiles and needs a Garmin to find his way out of a wet paper bag.
Stacey really wants to swap mechanic stories with gear-head, Mike, but she's bein' "car quiet" since her boyfriend is standing right there.

Josie's boyfriend is trying to do her a favor by taking her car to Jiffy Lube for her...But, she is so not going to let those hosers go anywhere near her car with Penzoil that she is unable to be "car quiet" about it.
