How does the aluminum block look? In Minnesota, older aluminum blocks start to show corrosion in the form of small white nodules on the surface. But not until 10 years or so. Something here does not add up. At 2 years, under the hood should look brand new or very close.
aluminum block is clean. My trade in, a 2014 Maserati, had much more “scaling” on the aluminum block/valve covers. But as far as the steel parts on that car was clean and nothing compared to this 2018. Heck all of my cars have been in NY for 6 years and none of them have this type of rust.
