Former homeless vet, needing a car

I am wanting to raise the money to place a good down payment for a good, reliable vehicle: https://www.chaconautos.com/vehicles/33745-2018-chevrolet-equinox-ls-2wd/ with payments that are at least $400/mo instead of the $1200+ I am currently paying for a month to month car rental. I am getting a service dog in the next 30-60 days and I would like for him to have room to move around when we are on the road. The rental car I have at the moment was the only option at the moment after my old car died on me and no one would finance a car without a high down due to my eviction in 2019 and repo in 2020. 

I fell on hard times after getting diagnosed with major depression and put on meds just as I was getting evicted from my apartment and followed with my SUV getting Repoed 2 months later. I have slowly climbed out of the hole I was in and am grateful for all of the help I have received so far from numerous Veteran organizations, charities and homeless programs, as well as my many friends, and coworkers.

This vehicle will help me in getting to and from my job as a security guard3-6 days a week so that I can make my rent payments on my apartment and into a better place in a year.

I am hoping to raise the funds in the next 7-10 days to get the car I am looking at and to return the rental I am currently driving.

Any and all support I get from this will mean a lot to me as I can continue with my journey of getting from under depression's thumb and start enjoying life again. All funds will go towards the car in question as well as the initial 6 month insurance policy.

I will be both thankful and grateful of all help I get from everyone who donates to my cause.
