Those are the cheapest of the Hazet screwdriver styles. The sets can often be found on some sort of offer, (about €20 if memory serves) and for that money they are good value! Not 100% sure they are German made, but they're good!
Wiha are good too. I'm not personally a fan of soft grip handles. They are fine for electrical fitting or carpentry, but hard to clean in a greasy environment! The blades are very durable though. If you can find these on an offer they will be similarly priced to the others. If not, they're still worth it. They are German made too!
For vehicle work, my choice would be (in fact was - I have a set in my road box) the Hazets with the hard black handles. Very tough, German made and clean up easily!
