I bought a great car for the price and payments i wanted. How ever a few miles down the road check engine light came on. They charged us to fix the problem and again it came back on. Took it back and they just reset the light. So again its back on. My ac dont work. Engine lights on. This car sucks. They said they would fix it for cheap. I just bought this car it shouldn't have this many problems already.
