The ones on CL are clearance kits that we have on the shelf. And black color for the sedans is not a kit I have in stock since it is not common on the sedans (opposite for the coupes however, I always have black for them).
I have sandstone and opal (grey) currently in stock and on special for the sedans. If you come and prepay for a straight black kit, I can order it in with the next stock order and there will be no additional charge for shipping. Then I can reduce the installed price to $800.
Again, this is for the straight black kit only. If you want the suede inserts, this is a custom order kit and the price still has to stay the same. Order lead time for straight black is about three business days. The custom kit will take about a week to get here. LMK.
