I'm looking at buying another used Audi and it is still under warranty and has Audi prepaid maintenance too. Owner has aftermarket intake and exhaust installed. He also claims it is being serviced at Audi with no issues and was just serviced. Regardless what he says I would still try to verify with my local Audi dealer directly and arrange pre-purchase inspection. I'm just wondering if anyone has specific experience with this or if there are any Audi dealers that can comment?
