I have both a 115 (240D Manual) and a 123 (300D Euro non turbo automatic) I like the 115 better. Not only does it look nicer with the more classic style, but I think it handles better. Plus being manual I can get high RPM getting into traffic if needed, something that I cant do in the non turbo 300D. The only downside, personaly, is the glow plugs being in a series in the 240D. Unlike the 123, if one goes out, the whole series is out and you cant start the car.
