Alldatadiy.com has a listing of all the technical service bulletins. There has to be at least 200 for a 1995 W140. Most are not recalls, but they do list potential problems one might encounter. I found my subscription to be very useful. If you decide to sign up, can I ask that you use this link? Thanks!
