lol, people who pay an annual (or every two years) fee to the DMV to make a personalized plate with the car name on it, when the back of the car already has the name of the car on it.
Even funnier, people who remove the stickers/emblems from the back of a vehicle, then pay the DMV to put the car model on the plate.
ie. "GTR" on a GTR, "C6" on a Corvette, "Alfa" on a Alfa Romeo.
As I have an Elise, and they're all around $30k, and the third most common question (after 'what is that' and 'how fast does it go') is, 'what does it cost', I was thinking of $15perlb, but they don't allow special characters so I might end up with 15 perlb.
