I always took it to be CYA (covering your ass) in progress. The chance of making a mistake after having a VIN number really gets cut down. It's less risk than taking what the customer says at face value. I know that fellow-Nasioc-ers are educated about cars but the general populace might not know the difference from the MY05 to the MY06. They might think that any Impreza is an STi and the list goes on. At least that's my two cents.
