Mercedes Benz Wonderboom

Mercedes Benz Wonderboom sold me a car that was involved in many accidents and defects such as engine malfunction, tyre sensors that are not functional, transmission problems and different paint works. Mercedes could not fix the problems for the whole year now, leaving me to have to bear the car malfunctioning with no solutions. Every time I ask for replacement, he will book the car for repairs and return it worse than before.
