Remember a tv commercial cutting a diamond in the backseat of an auto?

Question

Is anyone old enough to remember a tv commercial (I think it was for a car...ride so smooth....) where a guy in the back seat actually cleaved a diamond? What was that commercial for?

Answer 1

Volvo or Audi or Mercedes or something like that.  It was a commercial to demonstrate the steady ride of the vehicle.....ie you could drive over the bumpiest roads but yet inside the car you wouldn't feel it.

Answer 2

They were showing how smooth the car road on a rough surface, so smooth that you can cut a diamond perfect.

Answer 3

i think it was a lincoln car, i dont know what type.

i think there was an SNL spoof of it too.
