i can tell you right now that a 2003 toyota corolla most likely has 2-wheel ABS braking (since its a 2-wheel drive car-front-wheel drive). but there is a 50/50 chance that it might have 4-wheel ABS braking.you might have to check with the dealer for an exact answer.
to answer your second question, a 2003 toyota corolla should have an anti-theft system. if you got it from a private owner or a small car dealership, it might not have an alarm. thats another thing you can check with your dealer about.
