Xenon headlights

I just purchased a Infiniti G35 Sports Coupe. I love my car. Well I didn't know about the Xenon headlights and the high thieft rate on them. I got a introduction on Friday morning when I found my missing from my car along with a lot of body damage. Now I don't know what to do because I just got the car how can I sell it without losing a lot of money. No one seems to know what I can do to prevent them from being stolen again.

If any one out there have any suggestions I would love to hear it. Before I bring the car home again I will have a motion sensor alarm installed but I don't know if that will be enough since these thieft can take these lights out in 30 seconds.

Help me please

wow...thats harsh...I have nothing i could say but thoes poeople who did that to your car should burn
