Falkon: haha, that's kinda cool... I've been Aut0tek for at least 2 years on Quake 3 and in IRC and stuff... It's the brand of my car stereo amplifier... Autotek. It's good ****. ;-)
As for civic401: If you try to grind the number off and stamp a new one it will probably look ****ty and they'll be like: "You took the block number off blah blah blah we're taking your car."
And that **** would suck.
