Pretty sure thats a 600 SLR or AMG or something, you caught the vents right (top and sides), I didn't think the normal SL's came with the vent dealio? But hey I dunno much about MB's, not my flavor so you likely are totally right. It's a new car, and I agree with the bling wheels. With a drop though that thing would be sweet (Those are really crappy pics, I've seen it out and about and it's a different story from parking deck pics..)
The 635 is clean as a whistle, again crappy camera, it's a new paint job or something, it's 'cleaner' (the paint) than mine.. Sweet polished lip wheels too.
