Try using the subquery instead of a join.
You can simplify the entire query a good bit in the process. Here's a few hints:
- Try creating the subquery to return ModelID
- You could then use the subquery with IN as part of a WHERE clause
- Since you won't be using JOIN you also don't need to prefix the fields with the table name
