Hello guys, I own B7 A4 S-Line and I'm looking to buy an A5 3.0. I'm in touch with the owner of this car and I'm looking to buy it: Audi A5 3.0 TDI Quattro Sport Black RS5 Grille, B&O, FSH, Sat Nav, Fully Loaded | eBay I've been following the market for the past 3 months on the lookout for a good A5 that ticks my criterias. This seems high on the list. I'd appreciate any pre-buying guide/advice and questions to ask. Unfortunately the car is some 180 miles away. So I'd like to cover the groundwork before I go to purchase the car. I've asked about the DPF and intend to go in depth after a brief chat but any other issues I may be unaware of? Much appreciated A5 sub!
