Just googled them and was surprised to see they dont look too bad. It didnt look like they folded up or had any under arm storage. I really like the arm rests in the other audi`s because of the extra storage it provides in addition to serving its purpose as an arm rest
I really think you should consider the Sydmeko armrest. I have it installed since a couple of years and I just love it, perfect fit and looks nice. URL to sydmekoo is: http://www.sydmeko.se/se/index.html
A Swedish company but with an English homepage as well.
