Great choice, I love mine. Despite all the horror stories on costs I've done 10k in mine in 6 months and it hasn't missed a beat. It went in for a service yesterday and for the first time in a long time with any car it needed nothing more than the standard service. Enjoy.
I've just got back from a week exploring the Yorkshire Dales in mine. Apart from the mpg it behaved flawlessly. Some great roads, it got a fair few admiring glances too.
Everyone should have room on the driver for one estate. I don't know why but some cars suit being an estates better than being a saloon, especially when it comes to Audi's nice motor!
