I see.. I suggest that you send the photos to some of the junkyards listed at bildelsbasen and ask what they got. I visited one of the junkyards last week and found that they had a number of S/V70 standing in the yard more or less forgotten, without being listed on the web-site.. But they are all 20 years old and some are left with open doors or broken windows causing the interior to be more or less disastrous.. Anyway, I found an armrest for the center console (I also have the beige "oak" interior but with a different pattern on the fabric), not in 100% perfect condition but less worn than the original.
Maybe one of the "beige" leather imitations sold on ebay would do the job..? It will never be 100% color matched of course

I just cleaned the headrest, tried first with Turtle interior cleaner but the stains remained... So I removed the headrest and cleaned it using stain-remover, soap and dish-soap and rinsed with water under the tap! Pressed out as much water as possible using a towel and then allowed it to dry indoor for a couple of days with a table fan blowing air over it. Now it looks pretty good , almost as new!

V70 Mk 1 (P80) -00, sen ny. 66400 mil, klarar den inte 100k blir jag grymt besviken. What could possibly go wrong? Den är ju knappt inkörd

Borde byta packning på oljepumpen. Kanske blir besök på Volvoverkstad, många år sen sist
