My sister owns a 2006 A4. If you are looking for power, stay away from an A4 as they are very underpowered and pretty slow. If you want something in the same price range that is decently quick, go with a G35, They started making them in 2003, so they may be out of your price range. But check out a high millage one, they are great cars and just keep going. Before the A4 she owned a 2002 Passat, which she had many problems with. Same powertrain as the A4 and they also share many bits and pieces. The engine is great in terms of reliability, but they still have electrical problems after 30 years of the same old crap. The A4 drives great especially with quatro, but they are underpowered. The turbo is pretty much maxed out from the factory, so there isnt much room to move. Now you're saying that A4 3.0 is underpowered? Please.
