started my 1965 Barracuda today....

Wow, that looks an awful lot like my old '65 Barracuda.
It, too, was Ivory w/ Gold stripe, gold interior and it was a Commando-equipped non-Formula S car and was an original California car. It came with an option group called the Rallye Pack which was basically the 273/4bbl and the S13 suspension package (front anti-sway bar, hd torsion bars, hd rear leaf springs, hd shocks).
Here's a picture taken in 1990 just before I sold it:



It had a few unique oddities I've not seen on too many other '65s: factory bumper guards front and rear, remote driver's mirror and it had the exhaust tip cut-out in the rear valance, but never came w/ the exhaust resonator tip according to the original owner. I added the gold stripe, added a factory tach and factory am/fm radio (RARE!) and I added the exhaust tip resonator because it just looked dumb with that rectangular cut-out and a turned-down exhaust pipe.
I still miss that car and my wife and I would love to track it down. Last I heard it was in upstate NY.
When I saw yours I did a double-take. :)
