McLaren is in advanced talks about continuing its customer relationship with Mercedes beyond 2025.
Andrea Stella believes that is better to be a customer of an established manufacturer than a works team of a new manufacturer. A reference to RB-Ford and Sauber-Audi, or maybe remembering the McHonda days?

But I doubt they will win a championship without going the works route at some point
