Have heard a lot of fantastic reports about the Audi A6 Bitdi, over 300 hp, with quattro. Seemingly the torque is epic. They are a reality rare beast especially in estate model. I am wondering if there are any problems I should look out for, and in believe it doesn't have a standard gearbox, so was wondering if this was a good thing or not ? Also the claimed mpg is mid 40's which is hard to believe! I was thinking of heading to UK now that' the rate has picked up, but looks like a 12 or 13 model would set me back at least 10k? Any tips would be appreciated
