If you got rear-ended then it is an insurance claim against the other driver - or was it a hit and run? Your insurance company will tell you what body shop you can go for both claim estimate, parts...

With most junkyards still unfamilar with EV's, they may not remove the HV battery. The MB engineers (and especially the lawyers) are probably worrying about the car going to a shredder or crusher...

They dont even need that - there is no high voltage at the HV connection of a removed battery unless both the internal contactors are stuck closed - a extremely unlikely thing. All they need is a...
