Hi Golden,
I like this website to read about Angel Numbers. Here’s a link for 321 number if you want to read if you haven’t already.

If you see green cars...green is often associated with healers. I don’t believe that descending numbers are a negative really. It’s up to how you personally interpret them in relation of what’s currently going on in your life.
I see royal blue cars a lot. To the point it all most makes me want my next car to be royal blue.
God Bless!
