We just picked up an 09 B8 with 20,000 miles on it. It was a lease car and is a CPO car. It is easy to see how significant the body and engine change were.As with any used car hopefully we'll get a better engine than our 07 had. Having a mechanical engineering background as well as working with a lot of German model makers I still find it difficult to believe that Audi could not design a more oil efficent engine. We'll see what the luck of the draw will be.
