I'm pretty sure a lot of mid-80s volvos and up have heated seat elements. I almost bought a pair of leather buckets from an 86ish volvo 740 wagon, and they had the heated elements in them. I would think you could transfer the elements and put them in whatever seats you want before you cover them. Not to mention that volvo seats are usually pretty cheap. Hope this helps
