unroadworthy cars bad attitude

I bought a car from motorama in november since then i had problems with the ignition is damaged 4 shock absorbers are damaged and the cars tyres are worn because of the worn shock absorbers.i contacted the dealer and the dealer replaced the rear shocks and told me the car is fixed i took the car for a shock absorber test and al 4 shocks was faulty when i contacted the dealer they where rood and told me they dont sell new cars its my problem now .i would not advise anybody to to buy a car from them to spend 150 000 on a car and then you cant drive the car because it swerve on the road and vibrate and its dangerous to other road users so nog i have to spend another R5000 to fix the car after driving 600km with my road worthy car in one moth the car was at the dealer to be fixed for 4 days and its not fixed .
