I too was pleasantly surprised with the Soft Tex and Microfiber seats (the factory leather leaves a lot to be desired with the sticky Ultrasuede), for whatever it's worth, everyone that get's in my car thinks the Soft Tex is leather.
If it doesn't wear well, I will just have leather installed which was my original plan which I abadoned when I picked up the car and saw the black seats for the first time, everything just worked and it felt like a shame to throw away the nice seats. All the cars I drove at the dealer had the Ash panels but when they had to bring a car in for me to get the features I wanted (or didn't want) they brought one in that had the black panels and am I glad they did. It changed my whole perspective on the car, the black seats with the black car is a look I like so much I will deal with the heat issues. Originally I was going to get all Ash Grey leather interior seats and go for the contrasting and different look since factory was only available in a two tone look. Now, when I upgrade to leather, it's going to be black....
To Molson, I do remember liking the VW leatherette very much as well as the entire interior of the Passat but it's gotten its share of "bad" remarks regarding its interior quality in some reviews that I don't necessarily agree with, this was the other car I was considering but ultimately was concerned about VW quality and the fact that they are starting up a new plant. In 5 years when it comes time to replace the Crew Cab I will go back and look at the TDI Passat...
