Možné pomocí Sub-Query NEBO UNION je možné získat COUNT z více tabulek. Zkuste tento dotaz:

SELECT 
    (SELECT count(*) FROM `car_model` WHERE user_id=3 ) AS car_model_count,
    (SELECT COUNT(*) FROM `list_item` WHERE user_id=3) AS list_item_count,
    (SELECT count(*) FROM `part_item` WHERE user_id=3) AS part_item_count;
