Hello ai have these cool 928 Sport seats and
I am looking for info on the leather "color name "for these Late Sport seats. Its looks a bit darker then Navy blue almost black if you do not have good vision.
I have a 1987 factory brochure and does not look to be color from year 87 so prob option for later S4 GT and GTS
Please PM me if you have good info on these.
