Hi, Is there a site that lists the key differences between models? I'm after a new A3 (diesel I think) but am unsure what the pro/cons are between these models. 2005 54 Reg AUDI A3 2.0 TDi Sport 2006 06 Reg AUDI A3 1.9 TDi SE 2005 05 Reg AUDI A3 1.9 TDi I'm thinking of moving to diesel as the fuel economy of my 1.8T petrol isnt all that good. Thanks for any suggestions. Floob.
