BTW, while is is good to get a vehicle with low miles because many mechanical things degrade with miles, there are some things that degrade with age. The inside of the cooling system is one of the biggest problems that degrade with age.
Also at that age + 20 K miles I would be looking to replace the serpentine belt and tensioner, thought usually those are good for 25K or more now days, the older ones were only good for 25 K miles, and with 10 years of age I would replace both the belt and tensioner with idler pulley. Do not just replace the belt, the tensioner must also be replaced to maintain the new belt.
I would also drain the cooling system and fill with one whole bottle of Liquid Cascade Dishwashing soap in the Dark Green bottle, + water, and drive it for a couple of days, than (drain and fill with water and drive for a few hours to a day, at least twice), and drain and fill with Prestone Low-Tox (You can get it at NAPA). Be sure to have the vehicle facing down a steep hill or have the back of the vehicle jacked way up to get most of the water out, so you can get enough 100 percent antifreeze in to have the final fill consist of at least 50 percent antifreeze. The spring and fall when the ambient cold but above freezing are the best time of the year to do this because you can get by with water for a few days. If you use water only on hot days the water will not provide enough heat exchange to cool the engine. And of course water only would freeze if too cold.
Also if you want to really add some life to that trany, add a trany cooler to it, but get one that has the by-pass temperature control so it will not cool when the trany fluid is below optimal temperature. Trany coolers should be installed on the line that feeds from the trany, to the radiator cooler, so that on cold days the radiator heat exchanger will help warm up the trany fluid.
