We had an automatic 300D W123 and it returned as much as 16km/l, 14-15 more regularly. In town driving, still 9km/l. Highway speeds of 110-140 km/h, usually. Sold at around 280,000km with little trouble. The W123 230 & 230E are better buys, even. I had a 1979 230 and my aunt a 1981 230E. Both automatics and bulletproof.

35 MPG is about 14 km/L (7L/100km) - that's possible on this type of car since it's a manual gearbox. On flat American highways at constant 55 MPH (about 90 km/h) without the aircon on, but not if it's an automatic or if the aircon is on.
