One Careful Owner is an achievement in Mafia II.


Drive a total of 50 miles in one vehicle.


You will need to concentrate on using the same vehicle for all your driving until you unlock this. When accessing your garage, the legend will state "Distance traveled" for every vehicle.


  • In missions when you're instructed to use someone else's car, like Joe's or Henry's, you can often use your own instead.
  • If all else fails, simply drive one vehicle around until it unlocks.
