Bulletproof is just the beginning. A British car show did a multipart series of segments trying to ruin a w124 model, a 300te seven-seater 'station-wagon' and I think the cannonball ended it.
Lots of great features. The memory-adjusting drivers seat, third row, flat deck when seats were down that's just long enough to sleep on, the cargo cover, the crazy stable 5-point suspension and self-leveling system, sensitive AWD drive, skookum quiet sunroof, great wipers, wood trim, and ultra rugged mb-tex seat fabric. Also relatively safe, for the time.
