Help! Engine won't start.

A couple more questions:

Mileage?
60K service(s) done?
Last performed work on car?

mileage is 175 000 km (about 108 000 miles). Last work that was done was to replace the front rotors and pads all around, other than that, since I've had it (2 years now) I've installed a 3sx downpipe and a new cat, a K&N filter and a new IAC valve (black not brown). I don't know if or when the 60k was done, it would have been done by the previous owner.

*Edit* I'm pretty sure the 60K was done; I had a mechanic in town check it out for me as soon as I got it to make sure everything was in tip-top shape.

Gah this is annoying. I got it towed to my mechanic, they charge the battery and it starts fine, runs fine, no problems. They can't repeat the problem I had.

This is after me, my dad, my next door neighbor and the tow truck driver all tried to start it, to no avail. It now works fine. Thanks everyone who offered advice.
