I've driven a few DSG cars and for the most part I like it.
The only thing I didn't like, even in manual mode, is that if it thought it knew better it would select another gear e.g. at say 40 in 4th you want to accelerate using the torque of the engine and not change down to third, if the software thought that third was a better gear it would select it... in spite of my obviously knowing better

I guess that might have changed now as it was a couple or three years ago...
My GTD is a company car and it only made sense for me if I (a) keep the lease cost below my allowance - with Dynaudio, Advanced telephone prep (which as it turns out was a mistake because I lose the MDI port) and metallic DSG was going over (b) the extra emissions on the DSG car mean more BIK and more lease cost because my company applies a greater levy to cars with greater emissions... otherwise I might have spec'd it
The only reason I'm having the Golf is so that my 911 doesn't get used for the boring work driving...
