Looking to buy an A3 2.0 TDI, 2009 or 2010 and hopefully under 35k miles. I like the Black Edition, but only in red, is this a good/bad colour choice for later resale value, I'm not dismissing the S-Line or Sport either. What options are recommended? For me it must have climate control, iPod and Bluetooth. Any advice on buying these and any faults or things to look out for? Should I buy from a main Audi franchise or look outside? Thanks Hopefully I've posted this in the right section :-?
