The car is fantastic, extremely fast, it only has two flaws. One, in deep snow the car is too low so although it maintains excellent traction, snow builds up underneath so it can't go through more than 8-10" of snow. Two, the back covers on fronts seats, glue gave out over time.
Bought it CPO 3 months, 2K miles ago and love it. No issues so far-knock on wood. Very fun to drive w/ 6-sp manual. Interior is luxurious.. Armrest is a bit awkward-it covers the parking brake. I've cracked my elbow on it several times when it's lifted up. Armrest lid latch broke-this is a common problem. Dealer replaced under warranty. Overall, lot of fun to drive. Before buying, I drove two G35's and three 328i's, and don't regret for a second going with the Audi. The Infinity and BMW had much more power, but A4 was just more fun to drive. G35 had too much plastic in the cockpit. BMW oddly enough felt too refined - like it was driving and I was along for the ride.
Great driving feel. Interior, exterior styling. Simple and sensibly laid out controls. Excellent highway MPG.
Better armrest latch. Heck, better armrest layout. Incessant seat belt chime is too much. Rear leg room is very limited.
My first Audi (drove a 1.8T jetta for 5 years); this is one sweet ride. Gone is the turbo lag I had in Jetta, probably due to the Audi manual transmission. Nice smooth shifting, very good acceleration, fuel mileage has been in upper 20s, but car only has 2000 miles on it. The appearance of the grille is very sporty and somewhat mean looking :). I got basic car with 17" wheels, leather, bluetooth and iPod. The interior is beautiful and very comfortable. The ride is smooth and does this car love curves! Overall, the cost of this car is very reasonable. Overall, very pleased at this point. Highly recommend anyone taking a look.
