As some of these active safety features don't age well after over a quarter-century, I'm not really lamenting their absence on my '82 240D or '84 300TD, but I believe that BMW started offering antilock brakes on all their US-models in '85. However all those BMW models were continued for a few more years, not discontinued soon, like the '85 W123.

Happy Motoring, Mark
