Easiest cheapest way to fix dent

I wish I had more money to put into too. But yes regardless of how much someone puts into the looks of the car as long as it is safe and drivable all that matters is it's not rotting in a field or getting crushed for 150 bucks.
Not a lot of money here I raised 8 kids as a single parent and just got back into my old cars a few years ago. I have 6 boys that are helping me restore my car and if it was just me I couldn't do it.
Like you said do the best you can with what you got and use your imagination.
