Default 2005 V6 3.0 6sp Accord Coup Interference Eng or not? Timing Belt when?

Hi there I am a new owner of a 2005 Accord Coupe 3.0 with 6sp Manual. The car is 12 years old but only has 67k.. SO I have read lots of comments stating the 3.0 IS an "Interference" engine.. but I have not actually seen anything from manufacture? Then I see a couple web sites that specifically state 3.0 is NOT Interference?
And also this site

The "Gates" link that people reference often, does NOT actually state whether it is an Interference engine? but rather it just gives a mileage recommendation? (Or am I missing something on Gates link?) And besides do I really want to only take recommendation from a site that actually is selling timing belts?

I really have not seen anything Definitive, such as a Honda link or info directly from Honda literature? does anyone have a link from Honda stating "Interference engine" on a 2005 3.0 ?
I have one friend who is a local mechanic of 25+ years.. he has told me he has never had or heard heard of a timing belt split from age.. but from miles.. (I suppose there are different opinions/experience on this, so I figured I would ask here, has anyone had a timing belt with low miles break? Was it from aggressive or extreme weather driving? Or anyone have a water pump fail with low miles?

It is true MOST people use the mileage for their maintenance.. but there are definitely some out there that SWEAR by the age recommendation? I am 2nd owner so really have no ides how the previous owner drove his vehicle, I know he is 70 years old, From B.C. and he told me he kept it garaged in the winter & he did not seem the type to be an aggressive driver.
Thanks in advance for anyone if you can paste a definitive link? From Honda? (Not just a link from someone on a page who states it is on a forum)

Default Yes interference.

All Honda are interference style engines. You NEED to replace your timing belt when specified by Honda or it WILL DESTROY the engine. I think yours is at 105k. A quick Google will tell you for sure. All v6s have the belt. The 4s have a chain.
edit - the 4s from 2003 on.
