Cranbrook is very, very good, probably the most socially elite school in Michigan, and its facilities are the best of any school in Michigan, but, like any school, there are potential drawbacks.

It's the most expensive school in the state [[though Cranbrook, unlike most privates, has extensive private aid, due to big endowment).

It's generally considered a bit inferior academically to Detroit Country Day, which is a bit cheaper.

If you live in Birmingham or Bloomfield districts [[as well as a few others), the public schools are about as strong, so there's really no academic advantage to Cranbrook. The advantages are primarily smaller class size and snob appeal.
