We have a set with some imperfections for 2+2 made with full genuine leather, two tone, dark tan with light beige inserts, brown stitching and Z logos on both front and rear covers! This type of set costs around $850 shipped. I am willing to let it go for $300 shipped.
The front covers were installed once but were not used at all. There is an half inch cut on one of the back side of the upper side bolster, I can even include enough matching leather to replace the panel (any upholstery shop can do the panel replacement). Besides, there are 3 or 4 small scratches on the leather hard to notice....
Let me know if you are interested and have any questions.
