Is your car currently unregistered? And why is it so much to register it?

Some things that stand out to me that are definitely on the high side - the car payment and insurance (plus you don't include gas in your budget) and your phone. Selling and getting a cheaper car makes the most sense, but it's also worth checking if you can refinance the car and shop around for cheaper insurance.

Could you cut down to either Pandora or Spotify but not both? Even better, pick one from Pandora, Spotify, or YouTube.

Car wash is a luxury, not a necessity, so I'd definitely cut that one. (I did the same myself when trimming my budget.)

I would also see if you could shop around for cheaper internet. You might even save more if you change to a phone plan that also includes internet too.

Just some basics to get you started.
