That's a really gay thing to do but I bet your friend really wasn't phased by it seeing as how it required little or no effort to aquire that car. He was probably like "Oh well I got an Audi out of it". s**t man, I had to bust my ass to get that matching yellow tree air freshener at the car wash. If somebody did that to my s**t I'd lock them in my basement and hire someone to sodomize them on an hourly basis. That thing was rice anyway, and yes It probably had monetary value but not sentimental value like my junk box.
p.s. did he save the engine? the front didn't look bad.
