They look just like any other 116 but for the 6.9 badge on the back.

In the late 70's they were probably the finest car in the world and that would include the Rolls-Royce. They would do 0-60 in about 7.5 seconds but they only got about 16 mpg. They also cost $35,000.

Fast forward 30 years later to 2009... My wife's Pontiac G8 GT has every feature of the 6.9 except the air-hryd ride. It will do 0-60 in 5.5 seconds and gets 25 mpg. It cost $32,000 new, which adjusted for inflation is about $9350 in 1978 dollars.

But.... If you take the best Mercedes S-class today and put it up against the Pontiac I bet you would still think the Mercedes was the better car. GM has not stood still, but neither has Mercedes.
