Mustang GT 16

Worst experience I have ever had buying a car. Just over a 1 year ago I bought a mustang from them. Out of the 13 months. I have had the vehicle for only 4 months. This car has been in and out for repairs more than any other car I have owned. Had aircon problems. Eventually got the aircon sorted only to find the heating seats not working which still need to be fixed. Which they refused to assist with. Engine light came on more than once with miss fire error codes. Everytime the car went in they could not find the error codes on the car. Vibration on the suspension. Car not running straight in wet conditions only to find out after being in an accident that the wheel alignment was out and the car has issues with some suspension parts. Some parts still need to be replaced which I need to myself. I was told the car was never in an accident and had only paint work done on the right hand side of the car. Only to find out there was more work done on the left hand side of the car. Even old tools has been found in the fender of the car. Took the car in for service in February and they never even stamped the service book. Oil change message came on only 6000 km after the service was done. Services are booked every 20 000 km or once every year. Now I am Still stuck with the car and when you call their offices your calls takes forever to get answered. And if they answer you get transferred from one department to another
