Haved owned a '94 E320 wagon (previously) and a '95 E320 sedan (currently), I can swear by the W124 safety. The '94 wagon, traveling at 50 MPH, nailed a Jeep Cherokee running a stop sign. The wagon's was not totaled, its doors easily opened, and everyone walked away miraculously.

Anyway, the '95 sedan's bumper got pulled off accidently when my grandmother got stuck in the snow. Some people offered to help, but they attached a cord to the bumper...the rest is self-explanatory. I purchased a new bumper for $300+ new, but the paint was close to $250 as well. Since you still have the pieces attached, I would attempt a repair. Other than that, parts look pretty comprehensive.
