4.0l engine is a very reliable engine, if not overheated, heads would crack, but not too expensive to fix, for DIY.
Window issue could be motor, $80, or just a broken wire in the door to body harness(not uncommon)
You are in Calif. which requires Smog testing, often expensive if you don't pass.
131k is low miles so either vehicle was broken down a long time or it sat for a long time, either way the seals for engine, trans and axles could be dried out causing them to crack and leak fairly soon when driven regularly.
And if it was driven every week but only 5 minutes to work and back then engine never warmed up so it could be sludgy inside, this shortens engine life, which is 300k+ for 4.0l.
131,000 miles is 500miles a month for 22 years, which means it might not be too bad inside but........??
These are some of the issues with low milers, the only benefit of low milers is super clean interior and body, but with cracked dash.................??
Also check brake pedal, 131k should barely be worn, '93 has speedo cable which people often unhooked.
'93 is 22 years old, so will need general repairs just from age.
In my location $3,000 would be way too high, but used truck pricing is based on supply and demand, used Rangers are popular as service vehicles, although 4.0l isn't great for MPG but is good if you need to pull a trailer, i.e. gardening services.
And people like to have a small pickup just for around the house work, which maybe a past life of this truck and why it has low miles, wasn't used that much.
So yes, scout the local papers to see the pricing of similar trucks, I would ignore the low miles since dash is cracked, but up to you
