I think about five years, maybe a bit longer. Probably depends on loads and temperatures more than miles. Does the suspension pump up properly when you pile a load in the back, or has the control valve already been damaged? My W201 has SLS, when I got it, it needed a control valve (found a used valve for $50, works fine) and nitrogen spheres.
