I have alerts for Audi Avant 3.0 BiTDi's on my BCA Account and check almost daily. I also visit Auto Trader on a daily basis and also ebay. One soon gets to know the cars for sale and their prices, etc. The A6 Avant in the Auto Trader advert below (I wasn't interested) took around 2 months to sell, at auction and was last seen at BCA around 3 months ago. LINK. IIRC it was moved around the BCA auction houses to try and shift it, but it just would sell. On the mechanicals report, every box was green-ticked with the exception of the engine, that had a red X. Given that a lot of traders and those with a sound mechanical knowledge visit the auction houses and bid online, the engine problem must have been a stinker for the car not to sell at different sites for such a long time. Perhaps Arnold Clark bought it, or perhaps took it in part exchange, but knowing what I know, it's not a car I would trust without a clear explanation of what the engine problem was. Some poor sausage is going to buy it. It's cheap!
