The Lexol twins always seem to work well on any leather.
If you want to go with a one-step cleaner & conditioner, the Meguiar's Gold Class Leather Spray (Cleaner/Conditioner) is a nice product that doesn't break the bank.
I just detailed a Saab last week. The leather appears to be very tuff. I'm not sure if it's a synthetic or what be I think it will wear well. I used megs leather cleaner and conditioner. My trouble is getting the seat belt straps clean. Any suggestions?
