And you are right, the 400 series is the greatest car I have ever driven. Looking at a '95 S500 coupe this week to add to the V-8 garage!
I replaced the chain guides at 210,000 miles. I was starting to get some slapping noises, and when I dropped the oil pan, I found shattered pieces of the guides. I wouldn't worry about tearing into the engine until you get the symptoms. All the research I had done on the subject said that actual failure of the timing chain and subsequent engine damage is unheard of.
'85 500SEL, 245,000 miles (sold)
'92 400E, 295,000 miles (donated)
'84 VW GTI (work in progress)
'10 VW GTI (daily)
'72 Chevy C10
