My Audi A4 is excellent. It has 92.000 miles and continues in perfect condition. I drove it in Italy for a year and a half (miles a day - 110 - speed 110 to 120 miles per hour. I love my Audi A4 Quattro- is excellent.
I bought my 2003 A4 Audi at 95,000 miles. I bought it with a leak in the rear flange and it needed a new clutch. These 2 repairs together cost $2k My Audi now has 105,000 miles on it and I have not had any other problems with it. I drive it like a grandma shifting between 2500 and 3500 rpms depending on the roads speed limit and weather conditions. I test the acceleration about every 500 miles....
