I had reserved a Renault Megane diesel sedan with a manual transmission at an airport in France. (A highly regarded new model at the time, cheap to run in a place where gasoline costs a fortune.) When we got there, they said they didn't have one but we could have a gasoline engine, automatic transmission version.
We accepted - though reluctantly. This gas model was going to cost a lot to run and anyway, who wants an automatic? But when we went out to inspect the car, we found the door lock feature on the key fob wasn't working. We stomped back to the office - "We're not taking this."
"Would you take a diesel?" the attendant calmly replied, finally coughing up the exact model we had reserved.
I suspect the diesel 6 speed manual model was being held back for potential European customers, and they thought they could palm off the gasoline automatic on unsuspecting tourists.
PS That diesel/manual Megane was mostly wonderful. Lots of torque but no revs. You actually had to upshift when passing on rural roads! The biggest problem was we couldn't figure out how to turn the headlights on dim - we had brights or fog lights - which is not ideal in rural France. The manual had 5 pages of instructions on how to use the headlights - in French. My French is sort of okay but not good enough apparently.
