worst quality ?
I would not go that far. Maybe in electronic's.
In the few previous decades, the 70's 80's and 90's when the Japan cars were often called Jap Crap, and the FORDS Fix Or Repair Daily's
The Mercedes were not rusted out in Michigan like My Ford tarus, my accord and my Legend. ( After 8 years for Honda 3 for the Ford ) Here in the 21th Century the sheet medal is still thicker on a Mercedes than nearly all the rest.

So anyone want to buy Chysler ? Hear the Germans are giving up on it.
