£11k is not bad for the age. They are dreaming asking for £14k. But that's how most dealers work. They put ridiculous prices up initially and if someone takes it they make £3k on a motor right
Once it's been on the forecourt for 3/4 months they'll cut the price by 1500 quid and be happy to see the back end of the thing. Depends on the car of course. With a 335i the turnover is not as high as a corsa or something so they are willing to hold it for a bit in the bid for a higher margin.
