I guarantee if you do any brake, shock, strut, or control arm replacement you will wish you had the wrenches. Kent speaks from experinence!
Many tool sets do not even have a 16mm or 18mm combination wrench, let alone ones that have a ratcheting box end. Mercedes never used 16mm or 18mm fasteners up until the late 1990's. Now they are everywhere - especially under the car.

Both these long ratcheting box wrenches are high quality and make in Taiwan. If you own one of the newer models and work on it yourself, Kent highly recommends these. They can really speed up the job.
