Leather is 100% recyclable and is organic. Plastic isn't.
My wants aren't on the list:
Color choices that aren't lame
"Spirit airlines" bare-bones model that can be upgraded in the future
First off, welcome to the forums,
@ThurstonHowellV! Glad to have you aboard.
Two things: first, treated leather used in vehicle upholstery isn't recyclable beyond repurposing, but no one does that so it really doesn't count. Plastic can be, hence recyclable. I don't place much emphasis on this personally, but apparently its important to GM with the Hummers. I say just toss some good old leather in there, as long as it's durable.
Second, I should have added color choices, my bad. As far as a "Spirit Airlines" model (great name, btw lol), the best you'll get there is the base model, likely starting around $50k. It can't be much cheaper because of the cost of developing this kind of a truck. BUT, the interiors have been described as "utilitarian," so you may have something to cheer for there.
