C300 door replacement
The only negative I would see if they are also transferring the used window motor and regulator, but even then, only if those parts have issues.
The rear doors on my vehicle are rarely used... So as long as (a) the savings are transferred on to my bill rather than to their pockets, and (b) the door is stripped and repainted, I see no issue with a used door whatsoever. Even a brand new OEM door will have to be painted...
Anyway, I talked to both my insurance company as well as the driver's and decided it was best to replace with a used door. My only concerns with this were moving the tinted glass from the damaged door to the new door, as well as obvious paint blending/matching. So I talked to a few repair shops and they all said it was no problem. So I chose one that was close but not the cheapest (didn't matter as other driver's insurance covered everything). Needless to say, they transferred the glass no problem and the paint matches perfectly (Lunar Blue Metallic). Can't even tell it ever happened. The only difference is the motor in the replacement door is a little bit peppier than in my old door? Wouldn't really think it would make a difference as it was used but who knows. Also, if you bought your insurance policy and didn't specifically tell them you'd like brand new parts (this would result in a higher premium so they'd likely tell you) they'll only pay for used parts anyway.
