I had went out and bought a car from car hop witch was a 2000 Chevy Malibu it ran good for like three week then it started having rpm fluctuation I called car hops warranty and they said to take it to one of there shops did and all they did was take off the tires and said oh all your brakes are bad And your rotors I ask them if they could resurface the rotors and they said no so my car was deemed by them undrivable so I went a whole week without my car arguing with the finance company about if they were going to help me pay for this they finally helped me but they only paid for the parts I had to pay for the service witch was $405.00 and then the next day I went and picked the car up I asked them what they did to it they said " we put new brake calipers and new brake houses and the part that was missing a retaining spring for my drum brake and they resurfaced the rotors" when I thought they said that they were not resuarfible and when I drove it out of there they did not even fix the problem I brought it in for.
