I could see someone maintaining a 32-35mpg average with a well tuned 240D and driving habits that promote good fuel mileage.

What I was basing this on was not Craigslist, it was a magazine type drive test/report that was done way back when a 123 was new. As I recall, it was a steady state 50 mph, probabably flat roads, with little or no stop and go. I think it was done in South Africa. Unrealistic conditions compared to most driving in the US, I know, but they were probably trying to get the highest number possible to help sell cars. I did qualify my statement with a"when everything is done right".
Another point to make- most people I see on the road don't know, or don't care, about driving for fuel efficiency. They tromp the pedal to get going and fly up to stop lights instead of letting off and coasting. I live in a small town area where there is usually no need to drive like that. They are just "brain dead" about fuel economy, or busy texting, or daddy is buying the gas.
I think I still have that road test somewhere,if I find it, I'll post it. Later.
