Your second join probably has mismatched fields.

You didn't link to the challenge, but just looking at your query I noticed this part at the end:

... INNER JOIN Car ON make.makeID = car.CarID;

It's very unlikely that the fields you will be joining on would have different names. Look for a field name that both tables have in common and join on that instead.
