I bought my Audi A5 two weeks ago. I also considered a BMW 135, but I live in Canada so AWD is important in the winter. I also wanted a spare tire just in case (BMWs have run flats). First impressions are excellent. We had our first major snow of the season yesterday and the Quattro is impressive. I tried it in an icy parking lot where hockey skates would have been a good idea and the Quattro was very effective. The engine note is not as sweet as the S5, but I went for the better fuel economy. So far, fuel economy is not what I was expecting, but perhaps the engine needs breaking in.
