So I'm interested in having the seats in my pepper redone to add more bolstering and add an updated look along with maybe adding a vented feature as well. At the same time I would like to retain the factory heating elements since those work so damn well! I love the look of the sport seats found in the GTS and love even more so the seats from the 3rd gen cayennes. What type of pricing might I be looking at (I was figuring roughly $1.5k for all 4 seats). The leather in mine is showing some wear so why not do an upgrade vs just replacing the leather.
