"Traded in a BMW 335XI that was falling apart with only 50,000 miles on it. The Audi has been great. Zero issues. Vey quick, very responsive, phenomenal in inclement weather. The interior is way nicer than the BMW. The standard stereo is horrible though, at least the sound quality is. The MMI is great, and functions very easily. The 7 speed dual clutch is good. Not as good as a PDK but close. Feels a little laggy when starting off and waits way too long to shift into first when left in auto mode., but works great in manual shift mode and bangs of shifts super quick. The steering is a bit, electric. It doesn't feel as precise or as connected as the old hydraulic systems but it works fine. I usally set my personal settings to everything "Sport" except the steering I set to "comfort" as it feels quicker. The sound is pretty good too. Interior is quiet enough depending on the tires used and the engine in "sport" mode makes some cool noises with pops and burbles upon shifting. Cant hear any supercharger whine which bums me out, but some people may prefer that. The only thing i wish is that Audi had performance upgrade options you could purchase that wouldnt void the warranty. And the big "oh no I didnt know" when purchasing... If you buy an S4 with winter tires on it at time of purchase, the car will be limited to 130mph top speed for life. You can flash it and get rid of that, but it will void your warranty. This bummed me out. The car has so much power it will do 130 in 4th or 5th but the limiter kicks in and it wont go beyond, when it clearly has enough power to probably hit 170mph plus. Most people will probably never even get above 130 but here in Nevada when we take trips across the state, there's places you can set the cruise control at 120mph and just steer, so "opening" her up from time to time is a possibilty here, so it bummed me out the first time I tried and it stopped accelerating at 130mph. My old Subaru would do 155mph. "
