Not an easy one this, ideally you'll need to drive both variants back-to-back and then make your decision. I succeeded in doing this and went for the auto, I found the shift to be totally seamless, I've never experienced any delay, whether in plain auto or using the 'flappy paddles'. The auto syncro rev is truly sublime and coupled with a more 'sporting' exhaust will have you going up and then back down the box just for the hell of it, sod the fuel consumption. The only niggle is that it's best to let the box select 1st for you, and...I'd defy anyone to change gear quicker with a manual. I've been shouted down before for mentioning this but, there have been a few issues with the manual box, both here and across the pond. However, to the best of my (limited) knowledge nothing untoward with the 7AT has happened, maybe something to consider?
