Items 12, 17, and 18 are also on the "///M". Item 16 is no advantage. Still ... If your weight figures are correct (3131 for "///M" and 2944 for the 3.0), acceleration should be fairly close; possibly a high-5 to 60 for the 3.0, whereas the "///M" is low-5's. Anyone know if both cars have the same gearing in trans? My thoughts ... FWIW
