With the I6 engine, that mileage isn't horrible. Many of us get 250-300k on these bullet proof engines. Make sure the tranny isn't slipping at all, would be the biggest thing. Wiggle the cooling fan and make sure there's no wobble, should be tight, otherwise it's waterpump and possibly fan clutch time, which are actually not bad to replace yourself. Having a mechanic take a look at it would give you piece of mind and the best thing to do. Our platform has many quirks like all vehicles, but are easily fixed at low to no cost. There are some recalls to note. 1 being the brake lights, low beam relay, inside drivers side master switch, gas tank filler neck to name a few. While your year may not be covered, all years have these problems, but easily fixed. If in fact it is the I6 engine, runs good, no tranny slip, at a good price I'd buy it. FYI, we have timing CHAINS not belts, so no need to worry about changing that right away.
