If I lived in a colder climate, I think I would NOT daily-drive an MT car. I find they almost ALL have to be babied, until they get to operating temp. Sometimes it takes a fair amount of time to actually get to full operating temp (of course... for the ambient temp and for the load you are putting on the gearbox).
Why not? I never had any issues shifting a MT during the winter. I also never ”babied” my manuals. Start the car, put my seatbelt on, and go.
I guess YMMV. Personally, I have never driven an MT when cold that does not appreciably differ by way of smooth operation of the synchromesh from when it is warm. Unless you are an indiscriminate downshifter - it is when it is cold that the damage to dog-teeth of the synchro's occur.
