Yeah there is no reasonable way it is as new as the seller claims, but if I could figure out a way to get the device's age, I could call him out on it, use it as a bargaining chip and lower the price a bit more. Also the battery needs to be considered, if its a launch device, the battery might be on its last legs.
As an aside, your boot-loader is generally not modified by a custom rom. Such a change is technically possible I suppose, but unlikely. Or more correctly, I've only rarely ever seen it done, and usually its just a cosmetic change, nothing too fundamental.
