I think I also speak for BMW in thinking that there are few people that value the comfort of seats who would buy the crappy sport seats but sheath them in $$ Nappa. Because of that, they don't bother stocking Nappa on anything other than Comfort.

I've never, ever read of anyone that regretted Comfort seats...OTOH multiple people regret the Sport seats after sitting in them for a few hours. I know you carefully researched this, but I think you are a very small minority- anyone that is inclined to spring for the Nappa prolly says "Eh, only with Comfort? $900? No big deal, do it"

My 2 cents
