Lara,
i'm so glad your daughter got her car back. When we first got our van it was taken from a parking lot while my daughter and i were shopping. It was found the next day un harmed, but was full of used condoms and such... YUK! Needless to say we did some serious cleaning before we used it again.
I hope you guys can get your car up and running soon.
I know some people take the number 666 very seriously, like Jingle said, it has to do with the book of revelation in the Bible. Its the mark of the beast.
Take care and please just ignore that remark about demonic forces. sigh.....
