Separation is worthless and cannot be legally sold or transferred. More expensive is that you can transfer ownership. If you don't have a car, the license plate will become non-transferable. Without a license plate, a car becomes a used car without a real license plate.
For cars that cannot be transferred, the license plate is about 4000 (legally, the car and license plate are still the original owner).
The number of cards that cannot be transferred is less than 2000 (you must buy a new car to use it).
6000~7000 to buy a new car (you must have a card list to buy it).
Buy two empty cars from 2000 to 2500 (you can't get real cards).
