C5 III Review
I've owned this car from new. If you're reading this and considering buying, I wholeheartedly recommend it. Over 200,000 km driven, the car has performed flawlessly. Timing belt replacement was 3 times cheaper than in a BMW with a 2L engine from the same year. It consumes about 0.5 liters of oil per 20-25,000 km, which isn't bad considering I don't spare the car – full throttle on the highway, acceleration is great. The only thing missing is 4x4 drive like in Audi's Quattro. I know this because I currently have two new A6s. The air suspension leaves a lasting impression.
Pros:
Reliability over 200,000 km, Significantly cheaper timing belt replacement than BMW, Acceptable oil consumption, Good acceleration, Impressive air suspension
Cons:
Lack of 4x4 drive
