The manual / DSG debate is completely subjective. You would have to try it out for a prolonged period I think.
I jumped to DSG for my R more out of curiosity more than anything else after 30 years of driving manuals.
I only had it a few days and was going up a slip road to join a busy motorway.
Someone flashed me to let me in that was going faster so I put the foot down not realising the car was in 6th gear.
The car seemed to take an eternity to switch down to 3rd and by this time I had joined the queue and had slowed everyone down behind me!!
I was mortified.
Similar scenario at a roundabout, my car pulled out into a gap and no power.
I hated it and thought I'd made a really expensive mistake.
I posted similar on one of the forums and had loads of responses which helped a lot.
Basically the car doesn't know you are about to enter a gap in a fast moving motorway, or see a space entering a roundabout. It just wants to get you to 6th gear as quick as possible.
So you as a driver need to be switched on and take control in these situations.
In a manual you don't even think about changing gears it comes so natural.
In an auto you have this perception that the car does it all for you and yes it does but at certain times you have to take over.
Once you realise that it makes the auto so much more rewarding IMO
Plus with the DSG you can push the gear stick to the side and be in complete manual mode.
Heated seats are standard on leather cars and part of the winter pack on cloth seats. However the winter pack became standard from a certain year.
Infotainment, you had the Discover Navigation Pro that had the bigger screen, DVD player, hard drive that you could put songs on, voice control and I think VW bundled the Nav pro with Dynaudio at the time but maybe someone can clarify that. It was a £1300 option at the time and I can't imagine I'd have paid more for Dynaudio on top of that.
The smaller unit Composition didn't have the above features and you had to use one of the SD card slots for the map.

My wife had the smaller screen MIB II and I had the Nav Pro and to be honest yeah the bigger screen is better looking but there was no difference. We took her car away for a few days and by the end of it I certainly didn't miss my bigger Nav pro.
Same goes with Dynaudio I have it, she didn't. Cranking up the volume you are aware its different but for me not massively different.
