I bought her at 95000 miles and so far in almost 3 years I've put about 30000 miles on it. Just changed the timing belt a few months ago. This is a good thing to do when you go over 100000 miles. Of course I've had some problems with the abs module, and control arms that seem to be the common issues with this car. Most of the repairs to the suspension, brakes or rotors can be done by the home mechanic since the car is so well thought and with a set of wrenches you can do a lot. Also look for aftermarket parts since the ones from the dealer have some outrageous prices. Like somebody said "You have to pay to play."
Quattro, the V6 that came out that year still has no match to this day for that size, tiptronic that after almost 10 years still provides shifting without feeling it.
The 1999 Audi A4 2.8 Quattro sedan is a great great car. I've never owned a car that is so much fun to drive. It is everything anyone would want. It's comfortable, fast, sporty, luxury, and capable. It's an all around great car and I will always own an Audi. The two draw backs are poor fuel economy and premium fuel only. This is a huge expense and maintenance is really expensive. It is well worth the price. The car is now 8 year old with 110,000 miles and shows no rust, no signs of getting old, and runs like a champ. I tell my friends its a 99 and they say it looks brand new. Great car. A++
Heated leather seats, Quatttro, and the way it drives.
Bought my 1999 A4 2.8 manual shift used with 28,000 miles on it and have loved it every step of the way to its current 110,000 miles and counting. Ride has remained firm and car is solid and tight. I highly recomend the larger engine to the smaller engine with turbo, otherwise you're just going to be too underpowered and frustrated. It is important to remember though, that this is a german car not japanese and does require a certain degree of regular maintenance, which I've found to be $800 a year on average, all in, to keep things in top condition. I'd definitely buy another Audi!
Quick, tight, solid, and fun to drive. Trunk swallows luggage.
CV boots need to be replaced at a faily regular rate.
I have never had any part fail on me in 90k miles. It has however been expensive to keep just the regular dealer-recommended maintenance schedule. It seems like no matter what I get replaced, it's $1000. But car still runs great, starts every time without problem in Boston winters and still gets compliments 8 years later.
I bought the car used with about 90K miles. Worked fine until 110K. I have since spent over $3000. I've never spent so much on a car and I always buy cars around 100K. However, I've stuck to Japanese cars before. I've learned my lesson. I'm looking to trade it in for a Subaru. What every one else's review says is true. Fun to drive, expensive to maintain.
