I can understand why people react so strongly when a car is rebodied, but in the end if the registering authorities have no problem with it, and there is no evidence of theft of a vehicle involved, and it is "flagged" in a registry, then people can move on and the owner should be able to enjoy the car. Especially when it has been so heavily modified, its not like its ever going to be passed off as a "real" or rare cuda of some type. If all parties have knowledge of the rebody, there is no harm done IMO.
I for one am glad at least one nice mopar was created from the ashes of two.
Probably similar to buying a salvaged title car. It is certainly worth less because it is known (and registered) to have been totaled at some point, but if the car is repaired well enough to drive it, more power to you.
