Question is car related only in that cars use similar leather so the knowledge would likely transfer.

I bought this leather couch on craigslist for $30 yesterday. It is in decent shape except that the finish on the leather is badly cracking on the seats & arms. I know i an't make it look new, but is there any product(s) you recommend for cleaning & conditioning the leather to stop it from cracking and to prevent it from splitting? The couch looks not ot have been abused, but I don't think it's been condition in its whole 20 years.
