When I was deciding between the 60D and 75D for late December 2016 delivery, one of the tie breakers toward the 60D was the availability of the "old" black leather seats. I sat in the next gen seats multiple times and just found the bolsters too aggressive for my taste, so I love the seats I wound up with. I also am glad I didn't pay for the additional batter capacity since the 60D fits my driving patterns just fine.
