I loved driving my 220D (1970) on the highway. I think I got around 30 MPG. I think the 115 is a better highway driver than the 123 series - the 107 shares a lot of the suspension.
I think mine had power steering. The AC was after market, and I removed it to gain better access to the alternator. I have replaced the fan on two 115 cars - the first by the book. 20 hours is a good estimate - though I think it took me longer, I did it in one weekend. The second one was through the speaker hole - about half the time - one long day. Mine had the manual tranny - four on the column. Rust killed it (it's first 100K were as a daily driver in MN). I don't remember it being any slower than a 240D - but there were a lot of years between driving the two --- -- OK Don, KD5NRO Norman, OK "The Americans will always do the right thing... after they've exhausted all the alternatives."
