Man, some of you guys seem pretty uptight over an attempt at some small level of interaction. Ah well.

Anyway, heater vent under the passenger seat is the correct answer. No idea why my wife thought it was from the trunk; sound was clearly from beneath seat. My first inclination was something in the seat rails, because I didn’t even realize the car HAD floor level vents. 3 pennies, a nickel and a quarter. All from my wife - she who drops change everywhere.

Maybe you all knew about coins in the vents, beats me. But if you didn’t, and you get a mystery sliding, there’s a likely culprit.

(Clickbait? How in the world does that make any sense? )
