Where can I get Vehicle Parts?

In order to get vehicle parts such as tires, etc. You need to check places that have a high danger rating, and is usually inhabited by humans.

If you have the Sector Pass A item, you can head to the Military Bunker on the upper left area of your home. There are also vehicle parts that you can acquire in the Suburbs Laboratory. Be careful though since these areas have a lot of enemies, but they have a high loot rating.

Make sure to bring strong weapons, and have decent clothing for your defense. Having better back packs as well will enable you to farm efficiently in this area.
