I own a manual, but have driven the SMGII several times.
Not dealing with the clutch will be much easier for her.
If she can deal with the jerkiness, she'll be fine.
The key to SMG is to drive it similar to an clutch pedal MT.
Lift ever so slightly and shift and it'll be PRETTY smooth.
It's an abrupt tranny, there's no doubt about it.
The new e92 will also offer an new, upgraded Super Shift auto.
Supposedly, it's an AUTO, but it's as good as AMG's.
So, the torque converter is very efficient and you can paddle shift, like an SMG, but the Auto mode is smooth as an Auto is....
SMG in Auto mode is crap......
