Quattroporte owner damages his own car

It's not really the first time that we use to see something like this, but it looks like that in China, angry supercar owners prefer to smash their cars on public rather than risolve the dispute with their manifacturer. This time, the owner of a 423.000$ (yes, car taxes are huuuge in China) Maserati Quattroporte had an issue  with Maserati China and his dealership. His car after a wreck has been repaired by replacing the parts with again used and not brand new parts, and of course they charged him the service. Enraged, he decided to hire four people and hammers in order to smash his Quattroporte in front of Qingdao International Auto Show, a very strategic place to have a big media coverage.
