When I did some more research on this car it turned out that it was one of 11 Cutlass Calais cars used in a Canadian Economy Test Program in 1977-1978. Apparently they used the radio to dictate and record results as they were driving.
Here is an interior shot. As you can tell, the short throw European Opel based transmission looks very out of place with the rest of the car. The shift pattern is unusual in the fact that Reverse is located where 1st would be , and 1st is located where 2nd would be on North American cars. To get into reverse you had to move the shifter to the far left and forwards and not to the far right and rearwards. The first few weeks of ownership were confusing as I instinctively kept trying to put it in reverse and found myself in 5th gear, stalling out.
The car was strangely optioned too. No power windows but power side view mirrors and a power trunk. No air conditioning but a power moonroof. Fuel economy was outstanding as mentioned before - somewhere in the region of 32-34 mpg. I had a couple of friends I went to school with who had a '78, '79 Cutlass and an '80 Cutlass, and my gas tank would always last 50% longer than theirs. They just couldn't understand it. Even the local Oldsmobile club spent an entire hour crawling over, under and around it. I had no problems letting them test drive it either. Every time I took it to GM for service the mechanics were all over it.
These are the things that I miss that were associated with Oldsmobile. Technical innovation, experimentation, and the boldness and daring to 'play around'. It's a real shame.
