Rural Mail Carrier - $1,500

I am a rural mail carrier.
I truly love my job but I do not have a car that is suitable to deliver the mail.
As a rural mail carrier, we are required to provide our own vehicle.
I am at risk of losing my job, and sanity, if I can not find a vehicle to use.
I do not have a lot of money, but I am looking for an older car that has a front bench seat or a right sided driving car.
It’s gonna be drove down dirt roads and get banged up a little bit so I don’t need anything fancy, just reliable.
I bought a car that I could use and 24 hours after buying it, and only doing 1/3 of my route it broke down and the person has refused to refund me the money.
I just want to deliver the mail safely and in a car that I won’t break down in.
I don’t have cell service for parts of my route so it’s important that I can trust the car to make it back to town.
I am just trying to work for a living and support my family.
I can spend about $1500.
If you have something that you’d be willing to sell that has a front bench seat and some good space in the trunk or fold down back seats, that would be ideal.
Thank you if you’re still reading.
