Hi,
I have the 204 with ACC and DSG and currently touring Ireland in it. Just done over 1000 miles now on this trip and it is a really relaxing drive with DSG.
I hardly ever use the 'manual' option but I have found on a number of occasions it has been in the wrong gear when approaching a corner.
This results in coasting around the corner in 7th say rather than being in 5th or 6th and 'driving' it round.
I am sure there are ways round it (kick down or swapping to manual for example), but I am finding it a bit awkward at the moment.
Think either way you have made the right choice with the VW.
