I am thinking of selling my Audi A4 cab, 2008, it has 53000 miles and I have realised I have lost the service book! My car is worth about £9500, do you think having no service book will make a lot of difference to the value? Would it put you off buying it? It has 12 months MOT, new brake discs and tyres. I am feeling rather silly that I have lost it!
