When you buy an old Mopar, what’s your “gonna have to do “ list

Steering and brakes, it has to be safe.
Inspect the wiring, fix any hacked up crap.
Fuel system usually has problems, put a new fuel filter on it, and replace rubber lines.
A good tune up, plugs wires, cap/rotor and freshen the carb up.

Or just do the minimum to get it moving down the road, on my sons car, I got a quote to change the power steering hose, $400.
I would do it myself but the manual says to drop the engine cradle down. 97 Stratus.
I told the wife about the quote, she just gave me the deer in the headlight look.
But my smart-*** just said, I can fix it for $20, just buy a fire extinguisher for the kid to put out the fire when it happens. It was pouring fluid on the exhaust manifold.
She was fine with me paying to have that one done.
