Is there any authentic Hadith that describes the Prophet (May Allah's peace and blessings be upon HIm) as wipe ing his neck in wudu?
No, there is no authentic Hadith regarding wiping the neck. It should not be wiped.
See relevant fatwa by Bin Baz in Arabic or in English. In summary, there is a weak Hadith that Hanafi's followed, but it isn't authentic. A discussion of that Hadith and others can be found here (in Arabic). An additional reference is here (in Arabic too).
