My red 6.9 has standard valve covers. This is also true of all the genuine and suspected AMG 6.9's I'm aware of (eg, the classic centre car, mirafioriman's car, the silver one on german ebay last year...)
I have seen pictures of a few AMG'd M110 powered cars with that valve cover. Nice.
styria, when I first got the red car I did post a lot of pictures, but the only interior shots are of the front. In the next couple of weeks I will take a more complete set of interior pics. BTW I drove the car today, and the small steering wheel is sending me crazy - can't see the speedo between 80 and 160 km/h. Other observation about today's drive - cylinder 2's performance has deteriorated, and does not fire at all during idle - though seems to pick up when revs increase. I really need to investigate.
