All manuals are not worth saving. Dare I say, over history, maybe most? IIRC I've owned 3 manual Nissans (2 4th gen Maximas and a 350Z) and have driven some others. They are part of the reason I ditched manuals completely. Shifters that "don't like to be rushed", ridiculously long + heavy clutch pedals.... yuck. I used to go back and forth between Nissans and Hondas and the gulf between the transmission inputs was as wide as the Atlantic. I remember the exact moment I was in my 350Z where I thought "this thing would prob be better with 2 pedals". G37 proved my theory
