My friend loves the A7 and was asking me if there were any other cars to consider. Does anyone have any thoughts on what other cars to consider in that price range and whether it's worth the extra money for the S7? He usually buys cars and keeps them for a while if that matters. One car we did look at together (read: looked at reviews online) was the 6 series gran coupe but it's really not as striking a car to both from a performance (have to compare the 640 to the A7 since the 650 is almost 100K after options) and aesthetics perspective. He's looking to buy a car in the $70K-$80K range.
