One disgruntled owner of a previous generation BMW M6 was so unhappy that he used a sledgehammer to smash the performance car at the Frankfurt Motor Show.

Iranian-born businessman Pourmohseni Hadi bought the M6 new for €120,000 ($160,600) from a BMW dealer in Italy, but soon after that, he says the car experienced “serious technical problems.”

Hadi complained about vibrations, rattling and severe jolts during gear changes, and had taken the car to BMW Italy service centers ten times, but the problems were not fixed. Neither BMW Italy, or BMW Germany wanted to take responsibility for the faults, so he started a civil case against BMW Italy.

So to make some noise, he decided to publicly execute the M6 in Frankfurt. Check out the rage:
