This is cumulative. The first thing you should do before going for this achievement is to go for "May favourite color", "Slaughtermaster", and "The best car ever!". Once these achievements are attained you might already have unlocked this.
However, should you not I recommend going to the "Trainstation" map as there seems to be the most breakables there. I personally played through and got all my achievements by the time I finished getting gold on the last map. Then I had to go back and play "Trainstation" and with only one extra play of that map the achievement unlocked while I was still playing on the map.
