My Avanti, #4325,  building record was written on 4/30, but had no
final assembey date.  It has round headlights and the pirate buckels on
the doors,  but most different  is it has a total black interior...no
fawn color anywhere.  It is a 2 owner car, ordered from the local Stude
dealer in Atlanta,Ga.  It has the wood color steering wheel with a
black column.  None of this interior has been changed or painted...I've
had it completely apart...the dash is tolaly original (black).  I've
been told total black interiors were not offered before June of 63.  By
the fact there was no final assembly date,  makes one wonder if this
was a "trial run" car that got held up in engineering, just to see what
it would look like all black.  IMMIC, I believe that once the square
headlights came out, you could  still special order a  64 model with
the round headlights. Lots of weird things happened at Studebaker along
this time.

I believe that the first square headlight Avanti was S/N 48XX, built in
August 1963.  For many years, there were no round headlight front
panels available for use in repairing accident damaged cars.  There
were a lot of square headlight front panels available.  Over the years,
this has caused a lot of cars that should have round headlights to have
square headlights.
