If I have an MVC3 ASP.net page which contains a the model "`iEnumerable<mymodel.CarsForHire>`" - which links directly into an entity framework model- and I also now want to include the default user management model that MVC3 generates, how can I use both models at once?

I assume I will have to pass a collection in, or create a model called "`blah`" which has a field "carsforHire" which marries up to `iEnumerable<mymodel.CarsForHire>`, but not sure where to start.

Any ideas would be greatly appreciated
