Saw the 4kq, now is it worth it?

[Brendan Walsh]

So i went to see the 4k this morning, here's what i found
the bad:
Diff locks intermittent, front not at all, the rear worked 1 in five
times. (what a suprise huh?)
Tach was intermitent(i' would assume replcing the whole custer is
proably in order) tapping the top of cluster got it going again.
A-arm bushings need to be replaced, oddly the rest seemed to be ok.
Body had some minor chips/surface rust i missed on the first
inspection.Overall insignifigant
Idiot light for overtemp was flickering only when i was on the
throttle, assuming it's the sensor on it's way out.

the good
startes on first try, without  hesitation.
Pulled like a mother all the way to redline
no ticking clattering or other noises. 
clutch is solid
All hoses wiring and belts looked like new, no dry rot or cracking
all the paint was very shiny, excepting the couple chips.
interior was immaculate. 
all door handles and power stuff was functional.
no leaks in the engine bay. 
no evidence of water in trunk or interior. 

so basically i need some objective opinions, I think it's in good
shape, bettter than i expected really. What i need to know is how
difficult is it to repair the diff locks? assuming it's not a killer,
he's asking $2k Im thinking to offer him 1500, considering the unknown
mileage and difflock issues. Seem about right to you guys?

TIA
Brendan
