Obviously many of the remaining cars have been modified and
personalized.
But can anyone elaborate on, what I think are, the most common
differences:

Most cars have a hood scoop. But some came without it.

Many cars have a front scoop under the bumper as part of the body,
ala a
Mangusta. Most don't. (you can just make it out on the red one with
the white
top, if you go to the brochure in the photos section.)

Some cars have chrome strips beneath the doors with spring loaded
jack-
hole covers. Most don't.

The turn signal indicators, the blue high beam indicator, and the
green (non
operating on mine) light seem to vary in thier dash placement. As
does the
blank brass plaque on the glove box. ( I have an ad mentioning it
being there
so you could pesonalize your car.)

The license plate lights on the rear bumper vary greatly.

No side view mirror appears in the brochure (nor were there ones on
many
Italian cars of this era.) Did Ghia of Beverly Hills add them in
order for the cars
to be legal ? If so is the "correct" mirror the same as a barracuda's
?

I assume that all the cars left the factory with front end emblems.
Many are
now missing (not that hard to imagine). Also, obviously ghia made up
the
script emblem on the rear. Is the front one unique to these cars to ?

I also assume that all the cars left the factory with Plymouth "S'
options:
The cooling fin valve covers.
The low 16" "273 commando" air cleaner pan. (not the small, tall
ones seen
on many barracudas. And in the brochure.)
The exhaust resonator. (as seen in the brochure.)
Many of these are missing/swapped-out on these cars today.

Any thoughts out there. Other than I have too much time on my hands.

The above also makes me wonder about the non-plymouth parts. What
Ghia
bodied cars do they also appear on:
Headlamp bezels ?
The radiator (and expansion tank) ? I most often hear Maserati.
The dash switches ? Older E-Type switches seem to match perfectly.
The gauges ?
The tail lights ? I seem to recall this was mentioned in a recent
eBay auction.
The exterior door handles ? also on Mangustas.
etc.

I'm always interested in others' thoughts.
Cheers
