I managed to take a little video last summer when my 02 Silverado rolled over 200k miles (321868km for you metric types).The Bomb's total miles is about 88k, but I personally just passed 55,555.5 miles.
I was able to take a practice pic, but the camera died just prior to the moment with no where to turn off... bummer for me.
Also left my car at my local independent shop today. They programmed my BCM for my fogs, did oil and filter and tire rotation. Currently at 11091mi (17849km)
