 Purchased this car in 2014 after my 2006 A3 2.0T was totaled by a hit-and-run driver. The 2008 A4 had 28K miles from a warm-weather state and was a one-owner car from a vacation home - well cared for with full service records based on time, not mileage. I would have preferred Quattro, but the price and mileage were hard to beat. I should have listened to my instincts. Vastly different character than the A3... this A4 feels like a luxury car without any sporting pretense. The CVT transmission is horrendous - slow to respond in standard mode, jerky engagement from dead stop... in Sport mode, it holds RPMs far too long at low speeds before initially "upshifting." Engine vibration is far more apparent than it should be for any luxury vehicle - the same engine in the A3 was less prone to vibration. Brakes on the A4 are less direct, more difficult to modulate and with longer pedal travel than the A3 - might be fixed with stainless steel brake lines. Steering is much lighter and less dynamic as well; same with the suspension which is calibrated for a compliant, soft ride over handling - lacking the balance of a BMW 3-series. Lastly, the climate control is noticeably less accurate than the A3... the interior temp seems to be about 5 degrees higher than the set point during all seasons. Might be a faulty part or just the nature of the system - hard to tell and not worth tearing apart the climate controls to find out. On the good side, the car is indeed comfortable as a highway cruiser. The interior materials are top notch. The trunk seriously swallows more cargo than my wife's Ford Escape. Instruments are legible and direct. For the price paid, the car came well optioned for a 2008 model - although bewildering that certain features now standard on mid-level cars (like heated seats, Bluetooth and USB/AUX inputs) were nowhere to be found on my A4. It's a handsome car that will serve as a good family hauler for a couple of years - a car that I wouldn't be ashamed to take clients between point A and B. Lesson learned though - it's not a driver's car in the same way a 3-series might be. No major mechanical issues so far (knock on wood)... replaced post-purchase: an A/C diverter valve, the engine thermostat and the window lock switch. Not bad for a mid-2000s Audi. Overall, I'm not sure I would buy the A4 in this configuration again... at this price point for a used vehicle, there are more competent sport sedans and more reliable family sedans that cost less to operate.
