I just checked the VIN. It indeed has the troublesome rear suspension. However this suspension, when maintained as should, doesn't give any issues. I actually once looked at an '86 560SEL with 311K miles in which the suspension worked. The car had all its service records and the owner said he never had to repair it. All he did was maintain it as recommended by MB.

The chrome on the fenders must have been added on by the original owner or the dealer. I know MB had a "chrome appearance package" on these cars but that also came with chrome wheels which this car doesn't have.
