Where/ how does a girl get a car if ex ruined my credit?

1st: start by choosing better men- 2nd: begin a Zen quest to choose the one right car; this will be a car that costs $800, is low mileage, one owner, from the '70s and whose owner has died and his widow just wants it out of the garage- it could be a Plymouth, it could be a Ferrari- it will need $500 in repairs and maintenance- but you will have spent $1300, you won't be on the hook for payments, and you will have a mechanical friend forever- 3rd: this car will be hard to find, but it IS out there, waiting for you to love it, just as there is a smart, solvent, loving man, waiting for you, too
