I have both 1.9 ( m44) and 2.8 auto and 2.8 tu manual .
The decision on the 1.9 is easy manual is definitely better the auto box is only passable 1.9 manual much better
Reckon this would be because originally the box would be mated to a lazy torquey 6 cyl so doesn't like the high power band of the 4 cyl its ok if you are pottering around town but out on the country roads its struggles a bit to find the right ratio to be in if you demand power jumps down too many gears leaves engine high in rev range the changes up and doesn't use the engines pull efficiently.
The 2.8 auto is much better combo makes far better use of the engines drive characteristics ( as originally the 2.8 auto would have been in a 5 or 7 series) so big 6 mates much better.
Which is better is a difficult decision as for me depends what I am doing.
If going for a spirited country road drive has to be the manual as far more competent for that kind of work but for gentle cruise around or i town work auto is far more relaxing experience.
Never driven one in a zed but the later 5 speed auto as fitted to Mike's (
@mwpe) 3.0 is a far better box as i have driven it in various other bmw models and give far better flexibility compared to the earlier 4 speed so think auto wise in a zed best options are probably the 2.2 and 3.0 fitted with the later box.
