I don't have a problem with mods to a rare car. At least someone is throwing some money at it. Pretty much everything I own is modded. There is room for everyone in the hobby to do their thing. Personally, I would walk past 100 restored birds to check out the one with mods... but that's just me. The car was very rough, and somebody wants to put the time and effort to save it. That's all that matters to me.
Restoring a car to look "only" as good as the factory made it is like getting a boob job for your wife and having the doctor make them two different sizes to seem more natural
