I`ve never owned an Audi before, but Im very interested in purchasing a 98 Audi A4 2.8L Quattro. Some of my friends have Volkswagen`s and Audi`s and I think its time I get one myself. The only problem is I dont know a thing about Audi`s. Like I said, its a 98 2.8L Quattro with 180k km and Im buying it certified so nothing major should be wrong with it, I hope. I was just wondering what you guys think about the 2.8L engine and the awd in it. What should I look or listen for when I go take the car out. And is there any major maintenance that I`ll need to be worried about down the road with 180k km on the engine.

Any insight is greatly appreaciated! Thanks, Mitch
