What steps do I have to take? And how long of a process is it? 

My van's sliding door broke and I just don't see the point in trying to fix it.  It's easier to just buy a new one, but I can't do that until I ditch this one.
Thanks in Advance!

Call Premier Auto Salon and they will junk the car foryou and also give you any refund money back and find you a new vehicle at the same time. 080-5098-8728

Or contact the auto port and let them know, I think they do it for free. Some places make money from doing this so I'd check with the auto port and the salon place above.

I can do it for you on the spot. Just call me when you ready to go to VRO.
Autoport will take about 3 days in the name of FREE and you still have to take the paperwork to VRO then LTO in Yokohama. With me you dont have to do all that, I will take care of LTO runs and take the car off your hand instantly at VRO. Thank you.

From the above post about abandoned vehicles, you can read the entire article, but the jist of what you want to read I will post below:

According to Pare, people most likely abandon the vehicles because they believe it is a complicated and expensive process.

However , in reality, junking a vehicle is cheap and easy, because the NEX offers a free junking service, all a person has to do is turn in their vehicle.

If the vehicle is inoperable, the NEX can provide a towing service for a fee. When the vehicle has been junked, the NEX will return the plates to the owner. The owner is then responsible for turning the plates into the Land Transportation Office in Yokohama to de-register the vehicle.
