Saying hello - few questions

Hi all,

Just signed up to the forum having read a few posts for a while, so.. hello :)

Anyway, i've done my research into my next car, and my mind is made up, i'm getting an A5.

I've got a budget of around 16k or so, and i'm looking at either the 2.7 or 3.0. To now i've only drove the 2.7 and enjoyed the drive, but having read a few posts it seems I should go for the 3.0 quattro instead?

Also with my budget, I can get an s-line model with relatively reasonable miles on it, are they really worth putting more into it? As oppose to a fully loaded sport model with sat nav/heated seats etc?

Thanks, and look forward to seeing you guys around.
