How will you get proof of this?
So because a company has a strong image and produces quality cars, you need to bring them down when something goes wrong??? Seriously, do you listen to yourself sometimes?
All car companies have produced crap, whether it be Mercedes, Ferrari or any other car company. It's virtually impossible to produce a car and be able to 100% guarantee that there are no flaws or defects. There's only so much testing that can be done.
