Wynne, I've done almost the same move - except I went AWOL in an A3 for 5 months - definitely a low point, believe me. I'm in a GT blackline now and compared to the 159 I had and the previous 147s, it feels as well put together as the 159. It rides so well, better even than the 159 and the seats are just so comfortable. I got rid of the two really cheap tyres that were on the front and bought a couple of Pirelli P Zero Rossos and they cost a total of £200 fitted so they are loads cheaper than the 159's boots.
What I can't get over is just how low the GT looks next to other cars.
So what do I miss? I liked Blue & Me, The expensive feel of the aluminium dash and errr.... well..... everything else is there, different may be, but still there in the GT. I got a handsfree kit, Ipod adapter and well it's there now!
If my experience is anything to go by I'm sure you'll love it. Happy Motoring and good luck!
