We had the take home units too. I definitely took care of mine but I couldn't say the same for others, it could be hit or miss. I was the firearms instructor for 14 years and the care some officers took of their handgun, a tool that they might need to save their life, was sometimes appalling! You actually think they regarded their patrol car with any higher concern? I still say stay away from the police engine, unless you have first hand knowledge of how it was maintained.
