Stuff stolen from your car

I have seen people and had people ask me to watch their car if they go for a walk or food etc but I have never had to do that, I really don't want to start now. I called a performance shop and they can get me a replacement but it will be $25 plus tax..is it really worth $25 to steal..if it is going into a vintage car you should have some income to buy one...maybe he couldn't afford that and gas LOL
