Don't use my parking place or...

I have a marked parking place for my car in front of our block and I hate when someone visiting in the neighborhood uses my space and then I have to do this so he or she has to ring my bell and say that they are sorry and they will never do this again.
Until this guy, he got away and how he did it is a riddle. I only stepped away for a moment, but when I came back the car was gone - and I am mad as a hatter.
Tomorrow I am going to buy a chain and a lock, keep it in my car and chain and lock the next culprit to the fence (it is hidden in the trees) and then I can grin into his sorry face and say: "But I am not going to use the car until tomorrow so you have to come back then."
