2016 Sonata car

2016 Sonata, mileage is around 300,000. The body is in agency condition, except for the right rear passenger door, which has bodywork issues. As for mechanical problems, I don't know if the gearbox and engine are in good old condition or not, because the car has been parked for a long time. Asking price is 10,000 riyals. God is the guide and provider. The suspension makes knocking sounds.
