Should I get my car running driving as is OR

I would drive it and save up for upgrades as time and finances allow.
When you have the parts in hand, then do the work to it and continue that way until the car is done.
The first things on your list should be brakes, steering, suspension, fuel system, and tires.
Does the car have any structural issues? Electrical?
There's no use even driving it unless all of these are up to snuff.
My opinion FWIW.
How about some pics of this bad boy?
