After a long and arduous search and having owned many brands/models prior (BMW, Infiniti, Cadillac, Honda, Benz) I still keep coming back to Audi. Without a doubt Audi still makes the most refined and well thought out interiors in the world. I kept going back and forth between M3 and S4 and after much local searching was able to snag a low mile, pristine S4 from a private seller. Having owned an A6, 2.7T manual prior I was more than ready for a return. This car is amazing...it fits you like a glove, handles like few others on the road and is a practical hauler for life.
Interior, unbridled acceleration and steering response and stealth appearance. Will roast 99% of vehicles on the road and looks like a daily driver.
The e-brake/arm rest re-set is well known but a minor issue, a little more leg room in back would be great (addressed in '10 models).
