Greetings to everyone. I am new to joining the Forum but have taken advantage of the knowledge provided many times. I am a retired Mechanical Engineer who was a mechanic for 8+ years before college and have worked on personal MBZ's since 1984. Currently (72yr), I only do minor and routine maintenance on my partners fleet of four (4), (1998 S500, 2000 S500, 2001 S500, 2010 S550). But to be honest I rode motorcycles for 50+ years, so my heart is on 2-wheels. Just wanted to say HEY Y'ALL
