I absolutely love Audi A5’s, I think their proportions and lines are perfect. There’s a black one that’s usually parked down inside road near where I live, no identifying badges on it at all, just a pair of zorst pipes out the back, so I assume it’s an S-Line, but it’s very subtle.
I think the proportions are all wrong; to my eyes they look really, really bloated and a lot less sleek than BMW’s take on a coupes (4 series aside which doesn’t look right to me).
I think the E46 M3 was a great looking car, and much prettier than the following models. The arches etc give it enough menace / presence without silly wings and spoilers.
The Z4 coupe is a great looking car even if it is odd to drive being sat so far back.
The B5 RS4 is still a great looking car; it’s old now but still looks ‘proper’. One of the partners at work had one till recently and it looked lovely. I adore the following B7 too even though it is less subtle.
