I've been toying with the idea of an A6 for some time - with the intention of trying to get one in the Spring 2015. An option has come up for one a little earlier than that, but it doesn't have the Bose audio system that impressed me when I heard it in a car a while back. Two things, though:

1) Is the standard one "nearly as good"?

2) If one had somewhere between £500 and £1,000 to lavish on the standard system to upgrade some components, would that result in something as good?
