KNBS550

Hello! I just joined even though I've been reading the posts here for a while now. I have a 2007 S550 (W221) in beautiful iridium silver. I previously owned other Mercedes cars - 1997 S500 040 black (W140), and 1979 300SD (also black) (W116). Once you own an S-Class, no other car will do. I keep all my cars a long time, so all the technical forum discussions are very helpful. Thanks to those who contribute!
