Being a self confessed originality nut, I was intrigued to note that all of the panels on my MR2(except a couple) have a sticker with the Vin attached, ie., both rear wings, rear engine bay cover, both doors and the RH front wing, but not the LH front wing and bonnet. This feature is great for anyone wanting to check a car to see if it has had accident damage, less helpful when 2 panels don't have stickers and you wonder what has happened to it in the past :(
Quite a good feature in my opinion.
