I think it's because somebody stupid was trying to sell it to someone else who is stupid for 50 bucks. which leads me to say that stupid people should not have sex, they should keep their stupidity to themselves. If they insist on having sex, have sex with animals, and even then, use a comdom, Preferable an animal that is smarter than them, that way, if by any biological fluke they have offspring, the odds are, the offspring will be less stupid then them.
Ok, seriously though, lol. I just got off the phone with my local mitsu dealer. He said "two fitty". I was like "TWO HUNDRED????. He said no, $2.50 for either an uncut or a cut key. You can give htem your vin, and for 2.50, the'll cut you a key, or just get the blank key for 2.50. That was for a 1996 3000GT. So i figure it's the same price for all other cars.
