Never buy a second hand car from NTT

Hi

I bought a second hand fiesta ST roughly a month ago through a NTT GM dealership. I test drove the car and there were some faults that I noticed like broken air vents and damage on the paint of the car. The salesman told me that everything will be fixed if i decided to take the car. Everything went well, they put in a new windscreen and even washed the car. The salesman told me that the car had a full 101 check at ford and that there was no problems with the car. Its perfect. But i found out later that it was not true. I picked up the car and they told me to bring it back the next monday so they can fix whatever is broken and to do a roadworthy test. Upon takinf the car home and driving for a few days i noticed more problems on the car. The left front wheel knocks when i turn, the engine has a knock, the brakes were extremely worn, the speakers were blown and the centre console buttons were sticky. I took the car to them and told them about all the extra faults i noticed and they kept the car for over a week. After i got it back, half of the paint damage was fixed, the brakes were fixed but nothing else. Air vents still broken, knock on the left wheel still there, speakers still blown, centre console buttons still sticky and engine knock still there. I took the car back to them a second time which the salesman told me that he cant do anything about the damaged paint.. When it came back one speaker was fixed and the rest is still blown. And none of the other problems were fixed. I took it back 3 times which they couldnt fix anything. Upon taking it back the 4th time, the salesman became extremely rude with me. He told me that the car is under waranty and that i should take it to ford myself. He refuses to fix any of the parts and told me that its a second hand car and i should accept it with all the faults. He never told me about the problems i discovered. He never took the car for a full 101 checkup. If he did he would have noticed all the faults that i did. I feel that they should have had the car checked and fixed before selling it. And if they knew about deffects they should have told me before buyng it which they didnt. Now im sitting with a car full of defects. Paying my butt off. If i knew about the defects i would have looked for a different car thats actually in a good condition. I cant even use the car for its purpose because the knock on the wheel and enige makes me want do drive slowly, scared that it might break. I cant listen to music. Its driving me mad. I contacted the CPA and havent heard anything from them, they dont reply to my email. And im just really fed up. Im sick and tired of this ******* country and all the people trying to make a quick buck. Please help me. My contact number is ********** 487.

Kind regards JJ
