My ex threw up
in my (then new) '02 tacoma after too much fun at a wedding reception. It went all over the dash, down the a/c vents and all over the door panel.
After this I threw her drunk ass in the bed and made her ride all the way home back there. I cleaned it up with all the professional products we had at work, but on the hot days the smell still haunts my cab. I have to keep farting in there to drive out the much worse smell.
