I drove the second 300SD. It idled fine, especially after warm up. It did not have the body shaking vibration the first one did. The plastic cam follower on top of the engine that has vacuum lines running to and from it looked almost brand new (I think this has something to do with the transmission control). The engine was turning about 3000 rpm at 70 MPH. I was not sure if the transmission was in high gear(forgot to count the shifts) but all the shifts seemed at the proper time, and firm, but not overly harsh.The kickdown linkage could use an adjustment.

After returning, I opened the hood and the oil fill cap was leaking oil from it. It might have been turned past its sealing point,but seemed tight. Does oil leaking from the oil fill cap indicate anything negative?

The AC was working rather nicely. The driver side window motor was real slow as was the sunroof motor. The antenna motor was intermittent also.

The rear suspension was shot. Are these struts expensive and difficult to replace?

Thanks for the information.
