I bought the car from this dealer at the beginning of the year. The owner offered us 1-month warranty from the dealer or a contract with another company named "" GWC "" to give a warranty for 6 months. The dealer was going to convert his 1-month coverage period in cash to pay the price for the new warranty. We agreed and so we did. Within a few days after we bought the car it turned on the oil light on dashboard, I followed the GWC procedures and sent the car to one of the services that was part of their network. Initially the mechanic said that the car had the Brake vacuum Pump, some Gaskets although. And all of them were specified and included in GWC warranty. They never took responsibility. After this the car was still leaking oil. We communicated with the dealer and he said that you can bring the car to my dealer and he will send the car to his mechanic to fix it (I would pay the parts and he would pay the labor). After keeping the car there for almost a month and he did not answer on phone several times we went there to take the car when he confirmed that everything was fixed. At the same day we saw that the car was still leaking oil. When we gave him the car to change the Main Seal also asked him to change the brake pads. When we got the car, it was making a noise (one of the brake pads was mounted wrong) and still having the oil leak. After they changed brake pads his mechanic has lost the wheel lock and in overall, they don't have any responsibility. He confirmed to us that the main seal was fixed, but when we sent the car to another mechanic he confirmed that the oil leak was coming from the main seal (which means he hadn't fix it ).After I paid $ 800 to fix this problem he told me that he would pay half of the value but in fact he sent only $200 and now he does not even open the phone because he recognize my phone number.
