Since a lot of us have older 100's, I was wondering what everyone was doing (if anything) to clean/protect their leather. I want to make sure mine lasts nicely as long as possible. Was eyeballing some Meguiars single bottle stuff and the Meguiars 2 bottle clean then treat solution. Then again, lots of guys on my BMW forum swear by some stuff called Leatherique. Just wanted to see what people were doing before I went shopping.
