Talloulou, that really sucks. I'm glad that the police are finally taking the crime seriously and that you seem to be taking this in stride with a sense of humor.
You'll have to forgive me, but I was ROFLMAO when I read that the dimwit answered your cell phone. Reminded me of the Seinfeldl episode where Jerry speaks to the guy who stole his car.
Car thief: Hello?
Jerry: Hello? Is this 555-8383?
Car thief: I have no idea.
Jerry: Can I ask you a question?
Car thief: Sure.
Jerry: Did you steal my car?
Car thief: Yes I did.
Jerry: You did?!
Car thief: I did.
Jerry: That's my car!
Car thief: I didn't know it was yours.
Jerry: What are you gonna do with it?
Car thief: I dunno, drive around.
Jerry: Then can I have it back?
Car thief: Mmmm, nah, I'm gonna keep it.
Was there a garage opener remote in the car? If so, you should change the remote codes so your friendly neighborhood crackhead can't get inside your garage. Again, this really sucks. I hope your husband has backups of his files.
