My experience what to look out for:
-Climate control/evic lights being out. My radio also had a couple lights out.
-Power window operation (my switches are wearing out/dirty and have to play with them to get the window back up)
-My rear glass had a strut locked up so it was frozen shut. Cheap fix but something to try.
-Shocks & struts. If they're stock they're worn out.
-128k I just had all 4 ball joints done.
-A lot of us seem to be having front driveshaft joint issues lately.
-My back seat creaked when I got it (don't know how someone drove it for 116k with the noise). A little tape on the latch fixed it.
-Lately my rear glass has been hitting the hatch and rattling. Actually has worn down paint. Haven't had time to figure out the fix yet.
-Overall my paint is weak. Hood & front bumper look like the previous owner worked at a quarry. There are a few blemishes other places as well.
-My spare was cracked. It held air until we mounted a different tire on it. Couldn't see it without lowering the tire.
If you do purchase:
-If one day it just doesn't start try wiggling the starter wires. If that starts it up most people replace the connection, I cleaned it and put dielectric grease on and it's worked since (probably over a year ago).
-If it's cloth, the seats stain if you look at them.
And what to expect for mpg with the 3.7 - I fairly consistently get 17 mpg with my 2" lift and bigger tires. Much of that is steady 60 mph 2 lane highway. Pre-lift I think I got about 18 (didn't have it for long before lifting). I was as high as 21 on one road trip. Just because it says V6 doesn't mean it's better for fuel economy. If you live in a hilly area or do a lot of freeway driving I'd recommend one of the V8 options.
