The only thing with the V6 is the timing belt and VCM (Honda's cylinder deactivation system). The timing belt typically calls for replacement at 168,000 km. Given this car is 12 years old, it might be prudent to change the belt early since the engine is an interference design, and a broken belt will result in engine damage. Probably fine for now but something you might want to do in the not too distant future.
With the cylinder deactivation, those earlier VCM systems proved to have issues. I think that particular Accord might have version two which was more reliable than version one, but again, something to consider.
