Oh man, this sucks! Thankfully nothing got missing (yet :s)
I agree with people saying to use your garage, it IS the safest place for your car at night! The other stuff (junk?
) in there you might be able to store somewhere else or even rent a storage for.
Also invest in some good motion activated lighting and install it decently(so they can't cut the wires easily, this happened at my parents house during a burglary a couple years back!)
