Thanks, guys. A high percentage of highway miles helps quite a bit on the range (though I used to do a little better - closer to 650 for the warning light).
Of course, that was with stock nozzles and I'm running DLC520s (.205s) these days. Considering I'm not tuned, I can't really complain.
Might be time to consider a tune though, to better optimize for the larger nozzles (Malone's claims of picking up a couple MPG keeps tempting me).
And as OilHammer noted, it is an 01M, though it's technically the 3rd the car's had.
