A man and his friend destroy a 2007 BMW M6 in front of the Frankfurt Motor Show entrance.

Just to be clear, the owner of this BMW M6 isn't ready for another one. He and his friend destroyed the V10-powered coupe in anger at the entrance to the Frankfurt Motor Show in a decidedly public fashion. Bild and GT Spirit report that the owner was angry over mysterious quality and reliability issues that he claims BMW wasn't able to fix. What we have here, folks, is claimed to be a very expensive lemon.

As the story goes, owner Pourmohseni Hadi bought the 2007 M6 in 2008, and five years later, he is still complaining about mysterious vibrations, rattles and severe jolts during gear changes – the latter he says have caused passengers to become nauseous. The car was taken to several BMW repair shops in Italy and Hadi says he he has written a letter to the automaker about his issues, but the car was never fixed and the letter unanswered, he claims. What we don't know is how many miles the car has been driven and when all these problems started happening. The situation reminds us of a certain Lamborghini Gallardo from a couple years back.

While we understand Hadi's frustration, perhaps an M6 just doesn't suit his tastes. After all, we'd be lying if we said a perfectly functioning M6 of this generation wasn't bumpy over uneven surfaces and wouldn't make some passengers nauseous, with its stiffly sprung suspension and dizzying 500-horsepower V10. Anyone wanna bet his M6 was equipped with one of BMW's notoriously abrupt SMG single-clutch gearboxes?

But Hadi still isn't finished. He says the car will be repaired so he can destroy it again in Berlin to get his message across to BMW – despite the decal on the rear bumper stating in Italian, "Not Repairable." Be sure to watch the smashing protest in the video below.
