Well 2006 predates the upgrade in the head gaskets and about 100k was the average life of the OEM gaskets for the 2.5L engine. But most dealers mechanics have done this repair so often, and if you are due for a timing belt change anyway, they can do it cheaply and competently and it will be good for another 200k with the upgraded gaskets. Of course it will need one more timing belt at around the 200k mark.
But if the Honda has a timing chain instead of a belt, and you put winter tires on it, it probably is the best economic choice.
