I'm selling a salvaged leather seat skin set for the driver-side.
This was from my personal 1996 Volvo 850 Turbo, removed back in 2001 and stored in climate controlled ares.
It should fit any of the 850 series, not sure about the S-V/70 though.

It's a full driver side set, bottom cushion, back cushion and headrest.
Really good condition, no visible cracks or abrasions.
