We Buy Cars failed yet another customer

A friend bought a Mercedes c180, they took it to the test it failed. Had to pay for tyres and cracked rear light for it to pass roadworthy test. 10 kms from the dealer tyre pressure sensor came on, it was faulty. Few days later noticed oil marks on the floor where the vehicle gets parked. Notified we buy cars car got taken to a workshop, two weeks later workshop refused to touch it and advised it rather be taken to another workshop. Next workshop meant to fix the problems within a week but had to wait for tapet cover, then head gasket. It's been 7 weeks without a car and now my friend is convinced there's more to it than meets the eye. Sales who sold him the car is now on leave too. The car is still with Euro Motor Clinic who have also been making promise after promise. After googling We Buy Cars Brackenfell branch, Cape Town and Euro Motor Clinic picked previous similar complaints.
