This actually came up in conversation in the comments about nine months ago, but I thought it bore repeating:
One of my college roomates, Jim the Idiot, had a piece of crap car his last two years in high school. Never ran right, always on the edge of dying, maybe worth $300, but he put about a grand into it every year. Even though he was a pusher in high school, he could barely afford to keep it running. I guess he wasn't a very good pusher.
