my daily is a 04 audi a4 avant, 1.9tdi
i keep saying i'm gonna get rid of it for something newer
but i cant bring myself to part with it, been a great car
if your going diesel get the 1.9 as they're pretty bulletproof, the later 2.0 isnt as good and the 2.5 is well known for its unreliability
if petrol avoid the 1.8 turbo's, as they're heavy on fuel and have very poor performance
but they are generaly very good cars that will be happy at 200-300k miles if looked after
