October to September is a big gap!
I’m used to seeing 3-4 months from receiving my allocation to picking up my car at the dealership in western Canada (22 Macan GTS and 23 Carrera S).
Edit afterthought..Porsche communication is abysmal so I’m not surprised they dropped the ball on contacting you. My experience on customer support - my Macan arrived unannounced missing the electric steering column. I was finally told 5 mths later that I’d get compensation. 9 mths later and I’m still waiting. If I owed them a penny I’m sure the response would be different.
