Alfa still rustling?

‘moin, had my 156 sports car on the stage on Saturday to do a service, when I looked at the box a little bit from below while the used oil ran out, I found on the passenger side in the back two suspicious-looking brown spots around the semi-oval openings where the sweat water should run out under the carpet. I then lifted the underbody guard a little bit and already broke off the first piece of sheet metal, next to it in the next bead, got the rust The car is only 6 years old and already has rust holes in the floor. Why is the floor sheet not galvanized? Are the Alfa engineers Spackos or is that what they want? The holder that carries the charging air cooler is also completely eaten by the rust. Isn’t there a guarantee against rusting at Alfa? So a 2 g of ’88 ha t less rust than an Alfa of 2002……
