Actually, I went to another dealer today and checked their cars in the show room and the test drive ones, I am glad to know they all have scratched bolts, yet none of them got the rust; The salesman there suggests it's totally possible that someone opened the hood on a rainy day or could just have been left in the lot for too long; I wasn't able to check their stock cars though, it's in another lot off the premise;
So, I would say that car I was looking is FINE, I shouldn't assume it will have issue more than another Giulia;
BUT, I also found out that the car I was looking at was actually transfered from the dealer I just visited today after I paid deposit -- it wasn't sit in the port, but just the lot of another dealer; Gosh, I had been told how hard they were trying to proceed and deal with the custom the whole week, now I feel like a fool LoL;
I chose that dealer only cause it's next to a nice riverside park complex so I could spare some quality time while waiting for the service. I guess now I shall just try to get my deposit back;
