The 365 GT4 2+2 was only produced till 1976 but this one appears to be from 1977. Furthermore there are not many Pavesi builds known. The only thing I can see different on the interior is the wooden inlay. I have seen a similar thing done on a 400i Pavesi wich I came across during my hunt: http://erwin400.blogspot.nl/2013/11/the-hunt-part-iv-ferrari-400i-pavesi.html
This one can be yours for $ 58.500,-
Update: I just found this advertisement on the following website (I wonder what the price was). At least some more pictures on the interior, I will add a few more below for the records.
