I'm looking at buying an A7 Quattro diesel, either 242ps or Bi Tdi model. Anyone previously owned one or any techs for Audi can advise me anything to look for, recommendations of the two engine choices, I understand the bitdi models come don't come with the dct (or what ever audi's version is) gearbox. Is it worth sacrificing the more power of the bitdi engine for the gearbox or is the other box better.

Welcome any information or opinions.

Cheers
