Hey man I was in the same situation a few months ago. i couldnt get a job because i knew my car wasnt reliable. i finally got it somewhat reliable and got a decent job and while i was training and not making any money my car broke down on me 2 times once was a 3mile hike home and the other was a call to my mom for her to paypal me some money so i could go get a new battery as I was 20 miles from home. But now im making money and ive gotten everything fixed to where its drivable at least. Yes ive blown my motor up and am running on 5 cylinders at the moment but its still getting me to work and I have a spare motor in the passanger area and a cherry picker in the back. and im swapping it out next week. So just keep at it. You will get there
