Those are correctly identified as the Cordoba Biege LEATHER sport seats. I had the same seats in my 2006 MCS
and it was an infrequently ordered option.
In the US, the only leatherette (vinyl) seats in the R50/53 (2002-2006 MINI) range were black. There was also a very nice option called 'space cloth' that was black and grey fabric.
I could see not wanting to order a NEW car with leather seats as you would be increasing the number of hides required in the world by 1 car's worth, but on a used car, you really aren't saving an animal... I mean, you can't un-kill the cows from 2003. Oh well... It's not my car and I respect (though not understand) the ideas behind your question. Good luck!
BTW: MINI uses really crappy leather anyway. The Vinyl is a better choice unless you religious about taking care of the leather properly. If I hadn't loved that color combination with Pepper White, I would have gotten the space cloth or vinyl.
