Nice Spider! My '78 is the same color, AR 103...Avorio. It's pretty funny, people expect a red car when you tell them you have an Alfa, then when they see the Ivory, about 50% say they like it. My car has a lot more flaws and miles than yours, but I still enjoy it. I just sold another Spider, and I included the Turbinas I had on my car with that sale, so I've just had my Chromodoras powdercoated and put them back on. (With the turbinas, it looked REALLY similar to your car. (Just a bit more tired).
Last year at the Concours d'Elegance here in Seattle, there was a guy with a '74, I think, same color, that he'd just purchased from the proverbial "little ol' lady". Incredibly low mileage, original paint, virtually perfect except for a nose nurf which he had covered up with a bra. Mileage was something like your car's. I had wanted to shw my car, but once I saw his, I was glad I hadn't.
Enjoy it! -P-
