Yes it's got rust but at the price I'd be more worried if it didn't show some. As for the ASD, it's seeping rather than really leaking, easy to have a dry one that needs a rebuild too.It's rusty............look at the front wings, rear wings etc, also needs a diff rebuild, and on an auto locking diff that is big bucks, unusual and high specification mind you.
I'm surprised with the spec on the car it didn't have leather or velour. Then again, back then there was some really odd spec'ed Merc's about. On the other hand that makes them a little more interesting.Rare SLS on a coupe too! Shame it's not leather, but I guess it can appeal to some as timeless.
