I figured it eventually. (The only thing I don't know is where to put
the ORDER BY.)

SELECT
BRAND_NAME,MODEL_NAME
FROM TYPE
left outer join MODEL on MODEL_PK =TYPE.MODEL_FK
left outer join BRAND on BRAND_PK =MODEL.BRAND_FK
group by BRAND.BRAND_NAME,MODEL_NAME
having count(*)>1
intersect
SELECT
BRAND_NAME,MODEL.MODEL_NAME
FROM TYPE
left outer join MODEL on MODEL_PK =TYPE.MODEL_FK
left outer join BRAND on BRAND_PK =MODEL.BRAND_FK
where TYPE_NAME='xyz'
group by BRAND.BRAND_NAME,MODEL_NAME
