addict, I see you have a base XF as well. I bought mine because it did not have the leather seats in it (too much weight and my little *** slides around in them through the twisties) but after riding through the Dragon in a few SRTs, the suede really started looking better and better.

I went to a local company and talked to them about doing a 1 color suede (synthetic suede, much easier to take care of, no stains either) but like Infinite said, having them add a lumbar support and a few other little 'touches' like diamond stitching and they wanted $1,200 to do both seats. I do not think this is a horrible price, but I will keep me eye out for other options.

Hope this helps.
