Montresor is right, in my opinion. The "stolen car" is a metaphor for the isolation he feels after his failed relationship and the emotions he feels after it. He hopes to get caught ("Each night I wait to get caught but I never do"), but fears, and expects, to "ride by night and I travel in fear That in this darkness I will disappear" He fears total isolation from the people in his life.
