They were when I looked at used ones , the 5GT loses a lot in year 1, so the 530 vs 3l tdi that I was considering was comparable. After my last couple of BMWs Audi would have to do something special to make me give them money again from new / nearly new. The BMW doesn't look much inside if you like Audi interiors but the drive is excellent.
Seriously.....There's something about the way the wheels sit in the arches that doesn't look quite right. Have a look at some pictures over on the VWAudiForum in the C7 section and you'll see what I mean. They're the right design for the model but these to my eyes look as if they're not sitting right.
