Before I bought my Golf GTI with DSG I had a Mk6 Golf TDI, and a Honda S2000, which is generally regarded as having one of the finest manual gearboxes ever made, coupled to a truly great engine.
I've previously only owned cars with manual gearboxes, which over the years included several Golf GTI's, and a Caterham 7. As an aside, I've done dozens of laps around Goodwood, Cadwell Park, Snetterton and Donington, all in either GTi's or a Formula Vee. I can heel-and-toe with the best of them.
The DSG was, once I became used to it, a revelation, and coupled with Auto-Hold has really made everyday driving so much easier. You want to change your own gears, and fulfil those F1 driver fantasies? Put the car into "Sport" mode, push the lever over to the left, and flick those paddles like Sebastian Vettel! Or, as I spend most of my time in traffic, just leave it in "Normal", put the lever into "D", and let the gearbox do what it does best. In everyday traffic, you don't need to do anything else (apart from move the lever back a notch into "S" for a quick overtake).
Once you're used to a DSG, changing gears manually seems so archaic.
