I'm thinking of downsizing to a S3 from my A4 Avant 2.0T (220hp). The A4 is fairly economical and I can achieve about 38 mpg at a steady 80+ on cruise on a long run. I also carry 2 road/MTB bikes in the back (I can't be ar**d with roof bars) which fit in with the front wheels taken off and the seats folded flat.
What sort of fuel figures (real life) can I expect from the S3 and what are they like for luggage? Servicing isn't an issue as I have a really good team (Autotechnica in Hull) to fettle the car at good labour rates.
Anything I should look out for on a used one - apart from the obvious signs of it being rogered?
I looked at a Merc C class estate last week but quickly saw the error of my sins - the build quality isn't a patch on Audi's.
All advice appreciated.
