hello it is still hard for me to understand what your real problem is.

if golf and ford a metaclasses (classes of the metamodel) you can work e.g. with typechecks Golf.isInstance(car) or casts ((Golf)car)) or with typeSelect on a list cars.typeSelect(Golf). using this functions you can turn your car into a Ford or Golf and work with their attributes.

if they are just instances in the model (e.g. of uml::Class you have to search the subclasses manually depending on your metamodel. e.g. by earching all classes with car (direect or indirect) as superclass
