seeking car for Uber - $1 (SOMA / south beach)

I’m a career bartender, 31/f have been unemployed and down on luck making ends meet however I can.
I’m looking for a car I can make payments on without documented recent income.
I am approved for Uber but having trouble renting.
I have a friend with income who can possibly sign for me for a good car at a fair price with fair payments.
Dealers/salespeople welcome.
Open minded.
