2013 is the facelift, so that's a big plus. Probably one of the best looking cars ever made IMO, I like it better than the new body style. Like others have said, it's not the fastest thing out there, but it's going to look and sound fantastic.
I went from an A4 6-speed to an A5 8-speed auto as a DD, you would never guess how big of a difference there is between the 2 when it comes to how the car drives and handles. I was surprised by it, considering they're both on the same platform. The A5 is much more planted.
