I bought a 2017 used from a dealership in Phoenix area. We relocated to Florida and for the first time ever, I popped the hood and filled the windshield fluid. I looked up to grab the hood and there are signatures all over the inside lip of the hood. Is this normal? Has anyone seen this? I've researched a little and learned that the first batch of bolts were kept in Michigan, where my car was originally titled. Cool to think this could be a collectors item but maybe there are lots of these.
