Hi, I'm considering switching from a rusting 1999 Mercedes auto E240 and am interested in any advice on buying a used A6. I'm thinking of a 2000/2001 model and the 2.5TDI automatic saloon looks interesting. I'd appreciate advice on; is this much better than the 1.9TDI, is the "normal" auto better than the CVT, do they rust, what's the dealer service like and service costs? I've read reports that the handling is awful and that it's too harsh. Is this true? Will it be so different to the Merc? What about performance between 1.9 and 2.5? I want to keep it 5-6 years and will do about 10K miles per year. Any advice appreciated.
