There are some interior bits that I am not fond of in MK S as well, such as the IMO terrible looking air vent design both centre and side dash, and the centre stack needs something to break up the "too much" flat black facing, especially the large bit in front of the shifter. The LINCOLN lettering is not enough to mask this.
And the hanging planter in front of the fuel/temp gauges has to go. Everytime I see this I am expecting to see some flowers of some sort growing there.
IMO the new 2010 Lincoln MK Z dash execution is slightly nicer, but it still has some of the issues I mention regarding the MK S. Pic 2010 MK Z interior
http://jalopnik.com/photogallery/2010mkzpressint/1004698715@ Wastegate I have a feeling you do not like the way Peter Horbury designs cars, as he was the one responsible for the Volvo S80 ala same platform as the MK S is built on. And yes the P2 platform has been heavily modified for Fords use, but that said the platform has been modified big time for the MK S if compared to the Taurus.
Try having a seat in back seat of a pre 2008 Volvo S80 and see if you have the same issues as the MK S.
