Which one can hang with what and blah blah, is just useless bragging rights and nothing else.
There's a real world out there. 95% of peeps buy a street car to live with every day, and own and maintain, be comfortable with, enjoy driving, etc.. Not because it can "hang with a modded 335." If so, then you're an idiot. Oh, but I take it to the track. Oh, really? If you're doing real wheel-to-wheel you'd be doing it in your class and with restrictions. Otherwise you're on the track simply bettering your own personal times.
The RS5 will be a great choice for anybody that wants one because they like it.
