Look for signs of engine sludging. If they aren't run on synthetic they will sludge and consume oil pretty badly through the PCV system. Look for my "PCV Reversal" for high oil consumption. Mine was consuming at a rate of a qt every 300 miles or so and is now consuming next to nothing between changes. Pre 2005 models are prone. Also look for oil leaks expecially around rear valve cover, and front oil seals. Many people leave the seals alone when they do a T-Belt and they can begin to leak quite profusely around 150k to 170k. Other than this pretty bulletproof cars. Of course fluid changes are called for and spark plugs if have not been done. Change trans fluid use ONLY either a TRUE Type IV Toyota fluid or a something that is a true Dexron III. Stay clear of fluids that say "compatible with" WS, Dexron VI and a few others. A really good fluid is Valvoline Import in the blue jug. And keep the snake oil additives out of it.
Also front and rear differential fluids should be done by now as well
So just a few things here for you
