Worst Car dealership ever

i bought a car from this dealership and they said car went for testing and road worthy, i b ought hoping the car is in a good state as i asked the sales guy if there is anything wrong with the car and he said everything is good with the car you just need to add oil which i dd when i left the place. on my way home i had issues with the car when i reached 120 kmph car wasn't smooth, i then told the sales guy that the rear brake light and the guy doesn't drive smooth when i reach 120 he then said it is wheel alignment(but when i bought the car they said there was nothing wrong withe car) i then discovered than cv joins inners and outers needs replacement which cost alot. i also discovered that the sun roof leaks i told the sales guy about my problems he is been ignoring me ever since. i sent whatsapp a couple of times he is been reading my messages with no reply.

its only been 4 months since i owned the car but have discovered so many problems with the car.

i advice people not to buy cars from this dealership
