Suzie,
I feel so badly for you!
I would want to KILL if someone stole my bike!! Such a CRUMMY NASTY thing to do.
I've read that you really need a Kryptonite U-bolt type lock to lock your car onto a rack. I am pretty paranoid about someone stealing my bike, and I understand how upset you must be. I am upset just thinking about your bike.

Now....
Keep in your mind thoughts about how much you are going to LOVE your sparkling sleek fast NEW bike!!!!
