0.1s is neither here nor there, especially when you're talking about an 89.5 second lap on a track- a mere 0.1%. Could a driver like the Stig even put that down to more than natural variance in doing essentially the same time? It could be attributed to him knowing that car just a little better than he did before, having just done 2 laps in it on Normal and then Sport settings.
VW don't market it as a performance enhancing option, and i'm sure they would if they could.
You buy DCC for the option of making your ride a little softer when you want/need it on our poor UK road surfaces. The MQB chassis offers massive handling and comfort benefits over its predecessor. The MK5 and MK6 Golf on only 17" rubber as standard was harsh and crashy next to the MK7. For many coming from an older model, the standard ride will be comfortable and compliant enough. The only thing that went wrong with my first Scirocco under warranty was the DCC system. It failed twice, once each on two consecutive winters. I wouldn't spec it without a back issue for myself or a regular passenger.
DSG as an option? Personal preferences rule there. If you want to look a bit of a tit at the lights and use launch control then there's no denying the slight benefit off the line, but that one time in 50 that the DSG box doesn't do what I wanted it to do would annoy me immensely.
Dynaudio? Again it's personal preference, the moving car is a noisy environment and we're almost all using MP3s now, some below 320kbps bitrates. With all that in mind, I wouldn't spend the extra on Dynaudio.
I think we've been pretty lucky with the MK7 Golf's standard spec. There's absolutely nothing on the options list that is an essential for all.
