My Master Lock was the only one that the thieves couldn’t cut through.

My grandfather built a car in his garage when I was born. It was his favorite car and he loved taking me for rides. Unfortunately he passed away. He left the car to me. It’s stored in a offsite garage. Last week a bunch of the garages were broken into. My Master Lock was the only one that the thieves couldn’t cut through. That lock kept my grandpa’s car safe. I’ve already replaced the cut lock with another of the exact same lock.
