Thanks for that information. Too bad it cannot be viewed/inspected without removing the valve covers. So I am assuming there are no noises it makes when it is worn.

I just wish people would keep service records with cars, so the new/potential buyer will not have to play guessing games.

So, I guess it is best to assume that they have not been changed, if there are no records to indicate. I guess I will phone a few shops tomorrow to get an estimate on a chain replacement on the 85' 380 SE, as well as a 85' 500 SEL and 87' 420 SEL. All are cars I am considering, but unsure about the chains, except still unsure about the 87 420.

Thanks again.
