I remember when I discovered I didn't have ABS...about a year ago, I found out it was an option (thought it was standard on a Limited) and found out that if the light didn't light up during the bulb check, you didn't have it. No light. To prove it to my self, one morning it rained, and with no one behind me, I slammed on the brakes, and I skidded around. Better find out in a controlled test than after plowing into something.
