Endless problems

I bought a Ford Ranger doublecab 13 months ago from Liebenberg motors. From the word go, the Bakkie gave me endless problems. First the turbo gave in, which they reconditioned. Then the injectors was replaced by their mechanic's. Then the turbo broke again, this happened all in the first two months. A major service was performed by their mechanic's and a brand new turbo was installed. 9 months later, I took a 250km drive with my family and the enjin packed up. The Ford dealer gave 3 quotations, one for a reconditioned motor, one for servicing the motor and one for a brand new motor. All 3 quotes over 100k. My insurance Msure, are not happy with the quotes because they say it's overpriced and are only prepared to pay 20k. I borrowed money from my bank to pay Liebenberg motors which I still have to pay for 5years. How am I going to get all of this sorted because I don't have cash on my side, the dealership says it's out of their control. What is my consumer rights? The Ford dealer also only have a service history of 90 000 km on their system and the rest of the service history till 200 000km are missing, only the latest service record was found.
