I found a 2004 audi s4 4.2l with aftermarket exhaust and looks to be in amazing condition, but it has 160000 miles on it. The guy is asking 6000 for it and I was wondering if that's a good buy, if so what problems should I look for when going to look/test drive.

 

I would recommend you to check also the option of leasing. My favorite dealer is https://dsrleasing.com/. I have excellent experience with him and I don't trust anyone else.
