it's weird...but I spray WD40 on my leather seats on my E36 M3. It cleans, softens the leather, and conditions it. I've been using it for over 2 years now....usually spray them and clean them that way once a month. After that, I buff and use Griots interior cleaner for wiping down and just giving a basic clean.

Leather Cleaner and conditioner - Hyde Food
A very good friend of mine has been in the auto parts & service industry for 20+ years and has been with *gasp* a Mercedes dealership for over 8 years. He swears by Hyde Food and says it's the best product out there for keeping leather healthy, clean and supple. With our harsh summers here in the Phoenix area the leather has a tough life. our dry environment with auto interior temps of 160+, people damage (sweat much in Phoenix summers? and day-to-day issues are brutal to seats and upholstery.
Hope that helps!

Or Meg's APC at a 10:1 ratio - works well too.

Here's my experience:
