+Page 191, the method should be `CreateANewCar` instead of `NewCar()`, and the event `NewCarCreated` instead of `NewCarInfo` (also see page 190).

+```csharp
+CarDealer dealer = new();
+Consumer sebastian = new("Sebastian");
+dealer.NewCarCreated += sebastian.NewCarIsHere;
+dealer.CreateANewCar("Williams");
+Consumer max = new("Max");
+dealer.NewCarCreated += max.NewCarIsHere;
+dealer.CreateANewCar("Aston Martin");
+dealer.NewCarCreated -= sebastian.NewCarIsHere;
+dealer.CreateANewCar("Ferrari");
