Those are hard to find. Even P2 versions are hard to fine. Every one I have seen in the junkyards has been badly cracked.

I’ve combined the two - found a minty P2 wood wheel and retrofitted it into my P80. Here’s a crap photo since I can’t find a better one at the moment Image

I got lucky and found a good walnut inlay steering wheel in a PA salvage yard. Only damage is some slight flaking of the "clear coat" on the very left side of the upper inlay and a little bit of leather wear. Got it for cheap too. However when I purchased it over the phone they shipped me the entire steering column so know I have that taking space in my basement :|

Anyways, I should probably check my heater temp referencing your data. I feel like my heater core doesn't output as much heat as it should. Could be a result of the copper stop-leak crap the previous owner tried to use.

Love that wheel in wood and grey. Could use one for the T5.

Evitas is in beige.
