Macjake, similar story here. Worse, with a borrowed car! It wasn't anything special, but it wasn't mine. Quick jump to the end of the story: Friend wouldn't let me pay to have it fixed when I called and told him about it. So, I returned it with four new tires that took him a week to realize were added.
Didn't stop with the boot to the door, though, just happened to have a Permanent ink marker with me, and made sure everyone who saw that car knew the kind the person driving it. :evil: About the third time I scrawled the phrase (well, lets say it as an adjective and a pronoun, and leave it at that) of the four sides I monogrammed for him, I really started to feel better. But, the foot-print certainly wasn't enough.
Keep your markers handy, there are a lot of uncaring, insecure, jealous 'Adjective Pronouns' out there.
