I agree with Kevin above, but for my own reasons. I have the stock leather seats and I'm not thrilled with them. If I had it to do again, I'd get cloth and re-cover them with Katzkins or something like that.
Another idea... even though it borders on blasphemy, Steel Horse (IIRC) has a set of leather truck seats that look like they came out of a C5 Corvette. Seen 'em in many truck mags. He could also get aftermarket heaters (and massagers!) for them.
Heck, he could even pick up a couple of Recaros.
Hope this helps.
