@ Treworgey 90: Yep, I found that one as well, but aint we all
@ Tazz070299: The Letters are located on both the passenger doors. You can see them located above the doorshandels on the following pics: XIMG_2554_1 | Flickr - Photo Sharing! or on XIMG_2473_1 | Flickr - Photo Sharing!
They are silver, plastic letters and give the impression as if they have been there since new. They are located on both sides of the vehicle.
Can't really see them from the pics, but definitely non-standard. How about initials of a previous owner? (it used to be a cool thing to do at one time). Or somebody with dyslexia wanting to show their support Help For Heroes
