Why Do People Pimp Their Rides?S

Today's question hearkens back to Philosophy Week, but with a slight comedic twist. Seriously, yesterday's QOTD proved that we've all seen pimped rides (or at least what in the owner's mind qualified as "pimped") and with very few exceptions they're all pathetic. How many times have you seen a base model 300C with its anemic 2.7-liter V6 barely able to rotate the 22" dubs and sporting at least $5,000 worth of bling? Why not initially spend all that money on a HEMI? Or better yet, the SRT8 6.1-Liter HEMI? Who chooses looks over power? Obviously, these are the kind of thoughts that kept me out of the really good schools. But still, what possesses a person to do these terrible things?
