As for finding mint seats, you are better off accepting that they are going to be few and far between. It's may be better to find a set of Recaros for the right money and spend a bit more on getting them re trimmed. This may mean buying another set just for the material, but at least the finished items will be spot on.
I've just bought a set of so called mint 60/40 with headrests rainbow rears. To be fair they weren't too bad, but were dirty, had the plastic hinge covers missing and screw holes in the backs. I bought another seat from a GL that had all the bits on that I needed, stripped the covers off the GTI ones to wash them, then rebuilt them to make a complete mint set.
To me, doing this is all part of the fun.
