Another 100k miles shouldn't be a problem. My brother-in-law has a similar vehicle, a 2006 Accord coupe, with the K24 and 5AT. Black interior with dark grey metallic paint. He's at 100k with no problems on it. I've not met anyone who has had major problems with an Accord.
The more experience I have with the K-series engine, the more I like it. Even with the "economy" version of VTEC like we have.
