Hi James,
I have pics of the A5 shortly after picking it up back in 2010 and the S4 (dealer picture admittedly as I haven't had a moment to take a decent picture myself yet! Loving the S4 though, fuel consumption aside of course. I expected slightly more audible whine from the supercharger but it's so well insulated it's much more subtle than I was expecting. No disappointments so far!
Thanks for the welcome.
Tom
