There are many reasons to beat an M6 to death with a bat...wait, no, there really aren't. Unless you're this guy outside the Frankfurt auto show.
Apparently dissatisfied with his M6's reliability and BMW's customer service, Pourmohseni Hadi and his friend Thomas Brunner took to the poor coupe with a sledgehammer and an axe on the steps of the convention center where the show is held.
So what had gone so wrong that Hadi felt the need to demolish his V-10-powered specimen? According to Bild.de, the car rattled and buzzed while driving, and Hadi had tried multiple times to get the issue fixed through BMW's dealership network in Italy. After a series of unproductive treatments, Hadi sent BMW a letter, and, he says, received no response.
So he sentenced his M6 to public execution.
We can't say we'd take the same path--that's what the used car market is for, after all--but we do know the frustration of dealing with a lemon.
