It's a shame it's probably not genuine, but hey, rust free bike for sub $300. You could probably even talk the seller down to 200.
I have a brother that lives in Hawaii and the marine climate seems to destroy stuff pretty quick. I guess I don't know about the OP's area but here unless a bike is left outside all year round for a couple of decades or ridden in the winter the frame won't have much rust on it. Unpainted parts would. Enough people keep them inside forever that there's a lot of old bikes available in decent condition. Plenty were never that great to start with though.
I got a much nicer road bike than that alleged Bianchi for under $100 a few years ago. I'd probably have to spend $150 today, but definitely no where near $300. For that amount of money you could get something new from BD that's better quality.
Anyway, the bigger issue is that the seller doesn't appear to be completely forthcoming about what they're selling and that's a red flag.
