Finally motivated myself to join your forum after months of occasional browsing which I have always found interesting. Hope my comments here are also of interest to some.
I see someone asking about the price of servicing, well my 159 1.9JTDm Sportwagon just had its second service today and it cost me £300.00 which I thought was reasonable. The first service cost the same albeit via a different dealer.
Bit of history - I opted out of the company car scheme in June 07, looked at and drove the usual suspects - A4, 320d, Passat - then I saw the 159 - no contest! I actually bought the demonstrator there and then as it had most of the kit I wanted and more.
So far, after 40k hard miles (city,m'way + harsh local roads) I am very happy. Around 42mpg, 30k miles on original 18" Pirelli P Zero Neros (could have got more but they became very noisy). Few minor probs fixed under warranty but nothing compared to what my colleagues have experienced with their Germans. Very comfortable on my frequent 4-hour drives, quick enough and best of all, I don't look like one of the herd.
All the best for now
