I had got used to driving an automatic for my last three cars (BMW 530i, 530d and X5) but decided to give a manual a try to see what it was like to drive (to broaden my buying choice). I hired one for a weekend and although it was fine, I did seem to be changing gears a lot (I think it was a 140PS model so 180PS probably better). But the clincher for me was the handbrake. I am (I think!) average height for a fella at 5'10", with normal lengths arms, but it was just such a long way down to reach the handbrake for hill-starts. When I drove the DSG I know it was the right choice for me - very smooth and relaxed drive.
Cheers,
