Tires, tire pressure, alignment... My bet is that you have a tire out of round. I have a set of Michelins with lots of tread on my 300SEL but they have been on the car for a long time and have flat spotted and cause some vibration at 80+

Agreed, TIRES. And then find the cause of the tire wear - old age or bad shocks.

Replace steering damper.

...and idler arm...usually overlooked but quite the culprit if worn...plus, replacement is inexpensive.

wheels may be bent...this typically is what causes shake at highway speeds.
