I have had a 3/8" set for many years which is much more useful for auto work. I don't like going over 12mm in 1/4" because that's too much torque. It's still great for engine work like removing radiator brackets, removing air intakes, adjusting headlights, working dashboard, power windows, thermostat housing, etc. Do not regret buying the kit, swivels are indeed essential for modern automotive work, they are no longer a luxury item.
