Asking $400. These were made up 4 years ago by a local European upholsterer in Costa Mesa on 17th Street. Both seats are all leather except the backs. No tears, cracking, or holes. Seats were cleaned and treated regularly. Covers were used whenever the car was in the shop. Rails/slides not included.
Passenger side has rarely been sat in and perfect condition. Driver side has a wear spot near in/out by door. This can be sprayed to look original again-I have had it done once. Cushins and backs are perforated, arms are solid.
I am getting new GTS seats in early December and will have boxes for shipping-cost to ship is around $85---to be include in original price.
