I am doing this right now - I found tons of change lodged in the seat rails etc. Few pencils, pens, digital tire pressure gauge, gum wrapper, tons of dead leaves and piles of pine needles all over the place (behind the top motors etc). Nothing cool, thus far like what y'all have found tho...

 

Funny this thread comes up now. Just finished installing a new top on the car. Had dropped a bit under the carpet on the drivers side. Went to dig for it pull up what feels like a bit and I'm holding a live 9mm round. Pull up the carpet and find another one too. That could have been bad news in an accident.

 

3 air fresheners. Change. Police department card. Original documentation when the car was sold retail.

 

On my first S2000, I discovered aluminum spacers installed at the rear part of the driver's seat rails. The guy was so short I guess. I removed them.

 

"I swear officer, it came with the car"

 

I found about 20-25 black zipties in the access area for the softtop motor, along with the receipt for them and a dollar.

When I took my bumper off to clean my AEM filter a couple months ago, I found my original set of keys for the motorcycle. Been missing them for over a year (right around the last time I cleaned it)
Go figure.

 

I bought the car new off the lot with like 3 miles on it. I probably won't find anything in mine.

 

Just after buying my S I was cleaning it and found three big walnuts and some nesting material inside the front grill. Some squirrel had apparently made it into his condo while car was on the lot

 

I bought an 04 Civic brand new with 10 miles on it. When I got around to wiring up a stereo I found all kinds of stuff under the rear seat, none of which came from me.

 

when my s2k arrive to Panama i found some GAY sun glasses under the seats
