I’m the original owner and have done a lot of preventive maintenance as well as repairs over the years, but I still love the vehicle and it runs as well as new, I would not be concerned about taking it on a long trip. I have the M62 and gaskets have been a recurring problem, timing chain, valve cover, and the most challenging gasket- the dreaded valley pan gasket. Also, rear brake lines are prone to urgently fail due to rust at the exposed connections and bends, ask me how I know that. I don’t think suspension components are more vulnerable than other vehicles, bushings and ball joints wear out, and at 100k will need replacement. Welcome to the group.
