You pick the other door :) This is because when you first start, you have a 1/3 chance picking the correct door. After he has revealed an empty door. Your original choice still has a probability of 1/3 of being the correct door, the other door, however, now has a 1/2 probability of being the correct door. So by switching doors, you have a higher probability of picking the one with the car!
