I would not normally write a review like this, but I am so thrilled with my new Q7 TDI, that it felt necessary to share my thrill. I went into the Audi dealership, knowing I wanted a Q7, but was undecided if I wanted a practical V6 or a more powerful V8. I than noticed a Q7 with a incredible body kit on it, and a TDI badge on it. I test drove it, and was impressed with its massive torque and power. I walked out with it. Comparatively, it is bigger than the BMW X5 diesel, and more efficient. I have 3,200 miles on mine, and I average 19 city, 26 highway. Impressive, from a huge car. It drives beautifully, and does not emit a unpleasant odor or noise from the engine. It has everything you would expect from a large luxurious vehicle, and probably the best ergonomics in its class. The best dashboard and interior design too. I really only have positive things to say about this car, and could not think of something I would recommend more.
