Anybody had a 3.0TDi Quattro? I'm interested in servicing / economy / ownership costs and what they are like for reliability. I'm looking at an A6 (last of the outgoing shape), possibly manual. Also interested if anyone thinks the Bose sound system is any good.
I had a test drive in a A5 S-Line with same engine, and it was OK, but the ride was really hard, and it tramlined really badly...suppose i'd get used to that?
Any opinions much appreciated.
