I haven't worked on this material in a week or two, so everything is coming back rusty. I'm trying to do the INNER JOIN, but the hint suggests something I don't have in my notes:
"You're not fully qualifying the join e.g. table1.primary_key_id = table2.foreign_key_id"
I believe my code should be attached to the post.

The error message is trying to remind you that the ON clause needs to show which column of each table to use for joining, each qualified with the table name. Since the only column these tables have in common is ModelID, the ON expression should be Model.ModelID = Car.ModelID.

That's the query I've been using, but can't figure out what the equality criteria should be after the ON keyword....
