Difficult to say about the clutch, if one wants to, it does not take 100 km to burn the clutch useless. I assume your car had a genuine failure.
The turning radius is not a reliability issue. It looks like the stalling is an issue with the car. It should not do it but remember, if you were driving your Vectra, I believe it would not fulfil emission requirements for several European cities and the car would not be any better there than the B class when it stalls. A new car has a lot of electronics for emissions control and unfortunately some cars suffer from that.
A good shop should be able to diagnose the car and fix it so that it would not bother you any more.
