R58.000 to fix the car with Renault

My car stopped working/ Moving the Engine just went off. I called Renault and the car was towed to Renault in Midrand. the following day I was called and they are charging me R58.000.00 to fix the car. The car comes with 5 years warranty and to my surprise the car is out of warranty. that means I have finish to pay off my car cause i will pay the installment for 5 years. I don't have R58.0000 cash and I might as well buy another car with that amount. This is day light robery, e wanted to buy another car from Renault but I won't due to their service.
