You have UNTREATED leather seats - presumably someone told you this before you got the car. They mark and stain much easier than a normal car seat, but are also much softer and more comfortable. I believe they are actually saddle leather.
Your seats are more like a new leather jacket - if you get them wet, they will spot. If you get body oils on them, they will darken in those areas.
You could try and treat the seats with a leather protectant, but honestly, I wouldn't. That stuff will rub off on everything you wear in the car.
Much like a saddle, the seats will wear in over time, and will start to darken with age and use - enjoy them, they are breaking in as a good leather should, and will only become more comfortable with age.

It seems to stain easily with what I don't know. Some is from rain drops when entering and exiting. Other spots?? Also it seems to mark and scratch easily. Lightly scraping the surface with a cardboard box, my finger nails, or whatever seems to scrape off the surface. Using Meguiar's Leather Conditioner or Perma Plate doesn't seem to make much difference except to slightly darken the scrape mark.
Otherwise, so far, I think I am going to really enjoy this vehicle and my wife really like it. And I will appreciate any help with the leather. Maybe I'll just have to live with it.
