Just out of curiosity as I’m in the same boat. We ordered in February and were given an estimated date of 3 months.
2 days after the order, I got a Reservation Summary email from Peugeot/Stellantis (not the dealership) with a reservation number and collection date between June and August. The dealership has said their admin team are seeing late May for delivery but I’m doubtful.
Did you get your reservation summary email, and when did you order?
