Hi Randy,
Your green 1600S is an exceptional all-original Giulia. Roland said that even with a minor ding or scratch here and there, it was an amazing find. In fact, he commented that had you not bought it, he would have himself! That's saying a lot given the condition of the Giulias that he already owns. So, I'd put your 1600S as a grade above mine as far as condition.
It's almost apples vs. oranges though with the transplanted engine in mine. Your priority was low mileage original (which you got in spades actually with both cars), while mine was the combination of the best setup driver (original or not) in combination with the overall condition, especially lack of rust. My only restrictions were that it couldn't be bright red (oddly I really like "off" shades of red though and I definitely found one of those) and it couldn't be a Nuova model.
When I started drooling over Roland's own Pino green 1.3 Super with 2.0 transplant "driver" in preference to his gorgeous Bianca white first series 1.6 Super show condition example, I think he probably knew I'd jump on this one when it came on the market. Up until a couple of years ago the Prugna car spent its life in Firenze, Italy (Florence) before coming to Belgium. Several of the brake and suspension upgrades Roland did on his Pino car he is also doing to my Prugna car (stainless steel brake lines, upgraded rotors/calipers, sway bar, upgraded springs and shocks, rear trailer arms, etc.) because the parts had already been purchased for the car, just not installed.
Attached is a picture of Prugna in Roland's car port along with his Pino and Bianca Giulias. Pino and Prugna look like nice complementary colors to me. In fact, I just noticed that if you tone down the brightness of Pino and Prugna you get your two Giulias
