In my opinion the 3VZE are not as fuel efficient as the 22R-E, heavier, more complicated, had headgasket issues and only slightly better in terms of power coupled with an automatic transmission they are worse.See below for more info:

Check the back fenders and frame for deep rust by taking a hammer and tapping the back frame,also do a fluid analysis on the engine oil by buying a fluid/oil analysis kit from any Caterpillar dealer's parts dept or some heavy duty shops which would tell you how healthy the engine is if the engine oil and radiator coolant was changed regularly on those engines you can get at least 300 000 miles.
Remove the spark plugs and look at them as a picture means a thousand words if it has a manual tranny park the vehicle on a hill facing downwards then put the tranny in first gear and shut it off,don't use the parking brake or foot break if the vehicle holds itself well in first then your engines piston rings are great then you have high compression (no leakage past the rings),also when the engine is running remove the oil filler cap and see if you have b l o w by,a healthy engine should have a vaccum effect if you put your palm on the oil filler cap.
Finally if you have a portable air compressor perform a leak down test on the engine,for more info on a leak down test do a search on Google.
By the way find out where the guy works which would tell you if it has highway miles or city miles.Pull the ECU codes.
Here are some good starters if you buy it:
1)check all 6 spark plugs,rotor & distributor cap
2)clean throttle body
3)Replace front (exhaust/front pipe)oxygen sensor
4)replace alternator carbon brushes
5)Replace starter copper contacts
6)Lube brake bleeder screws,other parts including rubber suspension parts & spare tire assembly
7)Check 5 speed manual tranny pilot shift lever bushing & seat for excesssive wear and in auto tranny CHANGE THE FLUID to avoid shift solenoids from going bad
8)sandblast frame specially back frames if you live in an area where it snows and road salt is used then coat frame with

And in detail below are the above info:
Check all 4 spark plugs,rotor & distributor cap.Then clean the throttle body and replace the oxygen sensor.Also pull the ECU codes incase a part is an electronic sensor is faulty or bad wiring.
Usually excessive short trip city miles combined with low octane gasoline causes excessive carbon build up in the throttle body which does not allow sufficient airflow and hence the butterfly flap/accelerator plate to close all the way.
To clean the throttle body remove the air intake hose and examine the intake and throttle body for excessive carbon build if found then buy a can of throttle body cleaner labeled "safe on oxygen sensors,TPS's and catalytic converters" do not use carb cleaner make sure your engine is fully warmed up prior to using as when the throttle body is hot it dissolves the carbon easily and quickly.The labels usually specify to park the vehicle at ground level (0 degrees,no inclination) and have the engine running but I disagree I instead park the vehicle on a hill facing down and shut the engine off and hold a rag below the lip of the throttle body and poor the stuff and use a tooth brush.
