Great Car

This is my 2nd Audi and with one exception, it's been my favorite. Did have to replace transmission "computer" chip outside of warranty and they don't come cheap. On the other hand the car has provided wonderful service, It's stylish, comfortable, quiet, reliable and gets exceptional milage - 22 to 24 in town and 30 to 32 on the road at 70 mph. I am, however, a geezer driver - as my children tell me - so I don't flog either the engine or brakes.

Stage 3 black "s-6"

Initially, with low miles, there was no need to do any maintenance other than brakes and oil changes. After 40,000+ miles (approx. 125,000-130,000 on the odometer) expect the turbos to have issues especially if you're a spirited driver. Cost to repair is ridiculous if you aren't mechanically inclined. By this I mean a pro with engine lift experience, patience and an extreme love for the car. If not, expect to spend thousands more than the thousands the parts will cost you. I went stage 3+ when my turbos blew (passenger side to be specific, and also the timing belt) . After tackling the job on this car I have full confidence that I can fix any and all of the issues I may ever have. If you have the know how and the ambition this car is amazing and the engineering, when understood is truly awesome!

Extra horsepower is noticable. Rides on rails. Excellent in all road conditions. One of the best temp control systems in the automotive world. Hot/cold very quickly. Makes you grin when you push it.

Audi 3.0 FWD

I purchased my audi 3.0 FWD two years ago used (had 25K miles on it at the time). I was surprised with the average gas mileage(averaged 26.4 mpg) over the past two years. On the down side, I spent a lot of time in the shop for small items (some covered by warranty). Repairs included new battery, 4 cv boots, head light, two tail lights. On average I spent $1,200 per year in repairs not including oil changes, brakes and tires/rotations. Overall interior quality was less than I expected. The seats showed significant wear, the radio/heating buttons writing wore off and the wood (plastic) cracked during my two years of ownership. I previously owned a saab 9-5 and had none of these problems.
