i know i only have 10 years behind the wheel....half manual half automatic.
the g35 manual was a temperamental bitch.
the automatics in between were easy,lazy, and downshifting from a paddle is the most un-rewarding thing.
You seem to have no cons with the manual beside your partner. maybe its time for a new partner
but srsly. idk, the learning curve is steep, especially for someone who doesnt want to do it
