I live in South Africa and have recently acquired a '93 280E. From my research, I presumed that I was getting the same m104 engine that was fitted to the later E280. To my great confusion, the car's manual indicates that it has a 103.940 engine! As far as I know this is the old 260E (or 300E 2.6) engine. Displacement, however, is listed as 2799cc! What gives? Is this some kind of hybrid?
