2017 F23 M240i; B58 6MT. (Sorry, I don’t know everyone posts the flair).
I love it. Rev matching is nice. Changing from 1st to 2nd is a bear. I also find there is little difference in great ratio between 5th and 6th.
Also, driving a manual is really much more fun in an underpowered car. However, my B58 engine really does have a lot of power for daily driving, that there is often no need to downshift even for quick accelerations or steep hills.
In short, it isn’t perfect. But I still love it more than I would an auto-transmission.
(On a separate note, I did have an issue the other day, though. The ABS sensor started to act up. I lost cruise control, and then changing gears was really awful because the rev matching over-revved. The car was vibrating terribly. The next day, I lost rev matching completely, which was better and just did toe heel, then the damn computer warned me that the clutch was overheating. I always toe heel out of old fashioned habit even with rev matching switched on, so not sure where this nonsense was coming from. In either case, all problems disappeared after I got a new ABS sensor.)
TL;Dr - get the manual! It’s your last chance!
A big reason for this is to reduce air pollution. Studies have shown that air pollution increases significantly at traffic lights.
I am always taken aback when I see people sitting in their cars at parks or schools. Their unnecessary exhaust causes health problems. This seems to be very common in the USA. It’s less prevalent in Europe.
If you are stopped at a traffic light near schools, or residential areas, or busy pedestrianised areas like cities, think about others first. Keep the auto start/stop on.
