Iranian-born Pourmohseni Hadi and his pal Thomas Brunner were caught destroying the black BMW on camera, Metro.co.uk reported.
Hadi, who lives in Italy, said that he was so frustrated with his luxury German car since buying it in 2008, that he staged a protest by smashing up the car outside the world’s biggest motor show.
According to a German newspaper, Hadi complained of persistent problems with the car including vibrations, rattling and shifting jolts during gear changes.
Hadi has also claimed that he had taken the car to a number of Italian BMW workshops, but all of them failed to fix it.
Hadi added that he hacked down the car because he had sent a letter, detailing the problems with the car, to BMW, but he had not heard back from them.
