In most cases, the seller is not responsible for any repairs to a used car after it has been purchased, unless the seller provided a warranty or guarantee of some kind.
However, some states may have laws that protect consumers from buying cars that are not fit for their intended purpose, and these laws may require sellers to make certain repairs to a car before it can be sold.
As a buyer, it is important to get a thorough VIN report of a used car before purchasing it. This will help ensure that you are aware of any potential issues with the car and can make an informed decision about whether to purchase it.
Additionally, it is a good idea to have the car inspected by a mechanic prior to purchase. This can help you identify any mechanical issues that may require repairs.
If the seller is not willing to make the necessary repairs to the car, you may want to consider walking away from the sale and looking for another car.
