All 2000 and later 3 Series models manufactured after November 1999 include structural changes to improve occupant protection in frontal crashes (note: information about when a specific vehicle was manufactured is on the certification label typically affixed to the car on or near the driver door).
The Insurance Institute for Highway Safety has evaluated the crashworthiness of a BMW 328i with the structural changes in a 40 mph frontal offset crash test into a deformable barrier.

While cleaning out the attic I found a box of car brochures and magazines from the late 1990's and early 2000's most are in Very Good or Excellent shape.
