I just searched a4 trim and found a couple decent things. They have real brushed aluminum and real carbon fiberhttp://cgi.ebay.com/ebaymotors/AUDI-...16905022QQrdZ1http://cgi.ebay.com/ebaymotors/Audi-...10688521QQrdZ1

 

i was lookin on that sslrelay site a lil while ago and they had a crap load of trim options but theyre pretty price, upwards of 1200 bucks for a carbon trim kit

 

Ive got a 2000 A4 that had the ugliest trim some guy painted it green. I just removed all the trim myself its not hard to take to door off there are only 2 screws to take out. I just sanded primed and painted mine to a Matte Black. Looks good with black leather and black exterior, ill post pics when im done.

 

I have a trim kit in my car. I went with wood but you can put anytype of material you want in there. I think the kit looks awesome and i havent seen an other audi with as much wood as i have in mine so take a look. Iam pretty sure brushedaluminum also. Go to my pics and check out my kit and if u still intrested i can point you in the right direction.
