[Zope] Create subfolder at product creation

I have a folderish Python product called "Customer". When an instance of this product is created, I want it to contain a folder called "Vehicles" which is a normal OFS.Folder that will contain Vehicle objects owned by the customer. If I create a manage_afterAdd method in the Customer class, what does it need to call to create a folder called "Vehicles"? Or, if the manage_afterAdd is not a good way to accomplish this, what is better? Thanks in advance.
