The argument for a year old car over a new one goes for most things, year old 3 series against new Mondeo for example. But if you are going to buy a new car, then the new Superb will no doubt be very reliable, roomy and well equipped. As for the looks, well, yes maybe they could have been better, but I personally don't like anything that BMW currently do.
I own one of the current Superb's and it has been the most reliable car I've owned, as well as the roomiest. Remember, they currently start off at around £14k. There are lots of much smaller calls well above this price, that are not any better made or equipped.
Finally my 2.0 petrol is group 8 insurance!
