Which dealership was it, and what is it that's missing? They may have added accessories to the sticker and failed to put them in... but if so, and you can't get it resolved at the dealership, call Scion. They are VERY strict with their dealers, and will revoke their Scion selling capability real quick.
Hopefully you still have the sticker that was on the vehicle. Also, did you buy a different vehicle than the one with that sticker? Does your vehicle's sticker match your buyer's order? I'd be curious to see each, you can email me at
