Help with floor mats for an S4

[wackstar]

Hi all looking for some advice. My father in law has recently purchased a 2011 S4 avant its a cracking looking car but no car mats included. He is keen on a set of large logo S4 mats (Large S4 centre of front and rear mats) he has seen on line but has been advised these are not Audi standard and is keen to keep the car looking legit. Can anyone out there suggest where the best place online to buy this kind of fodder (he has a general distrust of all things internet) and which he should fit. He thinks they should be small vertical printed logos but we are not sure.

 

Please help.
