Hi, I'm hoping that some experienced Audi drivers can help me out here... I'm looking to buy an A4 2.8 Quattro from a friend (75k miles, R98 reg, auto, leather, BOSE, all other extras etc) and he'll take 8k for it. However, upon consulting another friend who runs a local dealership (and armed with a copy of Glass's guide) he informed me that £7,500 was the top retail price and £5,500 was the going trade rate. I'm very interested to know what other A4 drivers think.... Good price? Tad steep?
