5ktqw--buyer's advice needed

[Robert D Greene <RDG51@sprynet.com>]

I am looking for a 5ktqw, hard to find in good shape I know. There is
one around with 212K miles, supposed to be in nice cond overall. The car
reportedly runs nicely, no noise or smoke. Sounds like all the window
and dash type glitches have been addressed. The car was owned by
dealer's wife then sold to dealer mechanic, then to current owner, who
has driven it 25K miles without problem. Only major sounding mechanical
problem
is bearing type noise in rear diff.Any thoughts on what to look for or
avoid in such a car, and what the car is worth would be appreciated. The
seller is asking 3900 OBO.  Thanks  Rob Greene rdg51@sprynet.com
