I purchased this car new in November 2011 and now have just over 12,000 miles on it. It's been flawless so far. Not a single issue. Averaging 30mpg under all conditions. I can't say that about any of the previous Audi A4's I've owned--which were far more costly when comparing feature for feature. Great performance with the 2.0 turbo, plus excellent fuel economy for a sedan of this size--on regular unleaded.
Style; vehicle performance; fuel economy; passenger room, front and back; excellent seats; large trunk; heated front and rear seats; panoramic moon roof; voice activated phone; great nav system; best manufacturer new car warranty.
Too much wind noise from the side view mirrors; some road noise in the passenger compartment (probably from a combination of tire tread, road surface, and a lack of insulation); a good infinity stereo, but not great (woofer in the rear shelf vibrates when the bass is turned up); front passenger seat has no vertical adjustment; no 12V DC access in the rear pax area or in the trunk. All of these issues are minor compared with the overall excellent features, performance, competitive cost, and outstanding factory warranty.
