can you return a car recently purchasd
In most cases not, but it depends on the agreement you signed. Contact the seller/dealer too see if they will help repairing or buying back the vehicle.
In Kansas there is a 3 day cooling off period and Carmax has a 5 day return policy. There may be different regulations in different states. But I am with Tom on this, probably not. Why are you wanting to return the vehicle?
