I do wonder what BMW owners buy once they learn how to drive.

Under the back seat of the Contour I had in college I found enormous amounts of very long fake fingernails; behind the glove box a set of post-op instructions for breast enlargement surgery... They must have known each other

Rule number one of finding a thermos: you don’t want to know what’s inside

Dealer was supposed to remove that in PPI. 

I once bought a 1965 Corvair convertible for $35, with a structure so rusty the doors wouldn’t close. Beneath the passenger seat was a book of AA guidance, several empty vodka bottles and a thermos filled with vomit.

Was looking in my father’s BMW once and found this weird stick-thingy on the side of the steering column. Made a clicking sound when you pushed it up or down. No idea if it had any use.

Playing the long game.  I like it.

rehydrated potato flakes

Not my vehicle, but I was there when it was found.

One pair nearly led to my friend’s death and/or divorce.

Cloth seats are a trade off. They muffle the noises very effectively. However, they also absorb the smell so that when you go to remove the car seats, or whatever, you end up releasing a couple months worth of methane into your face. They also are a horrible pain to clean too.

I bought a Volvo parts car that had hundreds of 9mm luger rounds in the spare tire well- and a partial Canadian diplomatic passport

That’s like finding a pile of ‘ass pennies’.

Rainbow colored sparkly bikini underwear under the seat of the used police car I just bought.

Thinking that this sort of stuff probably happens more than a little, especially the no-sale, I kinda sorta almost have a little sympathy for dealer salespeople.

Not necessarily “weird”, but back in days of yore (like 2002) when I was but a young lad, I received a happy meal toy that was a little saucer with a metal ball inside that you would guide through a maze by tilting the saucer. After being entertained by this for 6 seconds, I realized the saucer was about the same…

One of the Previous owners of my BMW 850 wore loose pants and lost his change and frequented “Gentlemans Clubs” because of the change and cards I found under the front seat. I never did find that kilo of Columbian Marching powder which would have financed a full restoration.

Weirdest thing that I’ve ever found in a car?

The item wasn’t that weird...still finding it in the (you guessed it) Charger was.

Not mine, but we found this under the back seat of the ‘86 Monte Carlo my buddy owned and we were working on. Looked to be a half-loaded .22 mag.
