A car would be a part of the estate. If there is a loan on the vehicle, the estate has to determine what to do. They can sell it if it makes sense.

You can not register a car that you do not own. The car is owned by the estate of the deceased individual. The estate gets the title and then you buy it from the estate.

Some legal process must occur to distribute the estate of a person who has died. Usually, someone is legally named the executor of the estate and had authority to settle the estate in a manner consistent with a will, if one exists. If no will, exists, the executor still has the power to sell or give away the items owned by the deceased.

Technically, it is the estate which owns the car, with or without a title. If you want to become the onwer of the car you must have it transferred by the estate. It is the estate (and the executor is the agent for the estate) who must acquire title to the car.

With appropriate documentation, such as a certificate of death and legal documentation identifying the executor, the executor can request a new title from the State Bureau of Motor Vehicles. That title may be in the name of the deceased or in the name of the estate. The estate owns the car. Only after the estate has the title can the estate sell or gift the car to someone.

The estate can sell the car to the executor. They will have to demonstrate to the court that they paid a fair market value for the vehicle. Essentially, the executor pays the estate for the car and the estate settles the car loan.

The car goes into the estate. The estate may sell the car to cover debt and costs. They may also transfer title to the appropriate party.

Saloon and estate are descriptions of the shape of the rear of a car. In a saloon car the roof drops at the back and there is a trunk or boot at the back. In an estate car the roof line doesn't drop off providing a much larger boot space.

If you Google for "estate car images" and "saloon car images" you'll find some pictures that demonstrate the shape difference.
