Good Service but they sell Unreliable Vehicles

I recently purchased a Yaris from we buy cars in Silverlakes. The car was in excellent condition when it was first sold, but six months down the line this car began to not pump petrol at the petrol pump and I remember three months prior that so the third month of the car being home. The car stuck on the highway about twice, so when I mentioned to we buy cars the issues with the vehicle they told me “Once a car leaves the dealership, it’s not their problem anymore” so… I feel as of though the car is small seem good at first, but they don’t sell reliable vehicles and this is not a place where you should be spending money to buy your car.
