RPM comparison - owners of W210 606 motors...
At 70 MPH I was at 3K RPMs - seem about right? I thought it was a little high. I normally drive at 75-80 MPH and was thinking if I go that fast I'll be at 3.5K or 4K RPMs! I did search and found a thread where a guy had the same RPMs as I'm reporting, the rest of the thread was worthless but thought others might chime in with their observations - thank you!
