By the way, on the issue of wear, a lot of this is related to use. I read a really obsessive long thread once about "how to sit down."
The bottom line was that if you look at a 10-year old car, most of the wear is on the driver's left bolsters. So, it is not the age of the leather, but the way that it is natural to sit on the bolster and then slide into position. I would never be so rude as to instruct a passenger about this, but as the guy who puts 95% of the wear in the driver's seat at least I can do my part! I try to plop down in the middle and stay clear of the bolsters.
By the way, I use both Lexol products (cleaner and conditioner) with pretty good luck. Sometimes the build-up of the conditioner will lead to streaking--and I'll use 303 to cut it and reduce the luster, firmly rubbing with a MF. That works great.
I have a theory that leather care is like shampoo; you need to switch brands/techniques to avoid build-up. I was going to order some of that awesome smelling Griots stuff, but once again their $hipping is way too high!
