Small update:
So, I've nearly had the the car a month now, not done loads of miles, but after the initial central locking issue the car's been pretty much faultless. The tech in this car is a real step up from the S3 (both high spec cars).
First thing we noticed was how easy it was driving it round town and down country lanes. Never had a large car for a long period of time but it's probably easier driving down the lanes than the S3 as you're much higher up, so the additional width of the car isn't as bad as you'd expect. You naturally give yourself a bit more room though.
The 8 speed gearbox has short gears and it's going to take a bit more time to get used to, but the gear changes are fast, the noises are great especially in dynamic. Everyone comments on how good it sounds pulling away. But I need to code out whatever it is coming through the speakers (and i'm sure something is now I've adapted to the standard noises in the cabin). It appears you can set the car up in individual mode, but I think it does something to the exhaust note on the outside of the car too. I'm yet to tinker properly.
As expected the interior is a really nice place to be. No rattles and the build quality is nearly spot on. My only gripe are the interior door handles, the plastic looks and feels a bit cheap and over time i'll be surprised if they don't mark quite badly.
Distronic (or whatever Audi call it) is kinda cool. You set the desired speed and distance you want to remain from the car in front and it keeps to it. I use it whenever I can. My wife keeps telling me the car keeps driving itself including the steering despite the system being turned off so I need to find out whats going on. It's never done it to me and our settings are the same. And I didn't think I ordered anything that steered but whatever it is I need to figure it out.
The Matrix lights are awesome, I just go full beam everywhere and it sorts it out. Down the back lanes it lights up everything in site and dips sections when you come across cars. It even creates beams around cars in front going the same direction as you and you end up brightening up the road up for them. It must look weird from the car in front.
The B&O stereo is really good, i jump in the S3 (also with B&O) and it sounds like a set of tinny speakers.
Not a lot else to say.... I'll take some more pics when I give it a wash
