Views - Filtering view results by current user profile field
You can filter contents on their term_reference_field by the field_value of a term_reference_field of the current_user:

So we go:


Create a content_view 
Create a relationship with "favorite_car"
Create a relationship with "term from favorite_car"
Create contextual filter user:uid with provide default_value: user_id from logged in user and the relationship favorite_car


This works for me!
