I could be wrong. Either way I’m glad you’re at least thinking about preventing the break in, rather than just protecting the trunk contents.
All that any of us can do is make best guesses based on logic, trying to think like a criminal, and study the most typical MO's. And I agree with you that *thinking* all the way through this is important. Far too often we see people post the ONE WAY to best protect the car. But it turns out that I've seen about 50 (Yes, I have them listed) "this is what you need to do" or "this is what you're doing wrong" from online experts who claim to know how to solve this. And of course about half of the ideas conflict directly with the other half. The one that impresses me the most: Don't put anything in the trunk, and leave the seats down. :sigh:
I'm almost embarrassed to admit how much time I've been thinking about and studying this problem since my break-in exactly two weeks ago. It took a week to have the glass replaced, and another week to replace the tint. I'm now back to where I was... at least on the surface. UNDER the surface, I've done quite a lot in that time.
First order of business for me was definitely to protect the trunk contents. I can give up a window, but I can't give up my gear. My trunk is now FAR more secure than what comes from the factory. My seatbacks are impossible to fold down from the cabin, and a pried trunk lock will not open the lid. All of my solutions are hidden and would require so much time and effort to defeat, I can't believe that I'll lose any cargo now. I'm quite happy with all that, and now I'm turning my attention to preventing the glass smash in the first place. As things stand now, they won't have even a small clue that trying to get into the trunk will be wasted effort.
I really DO think that alarm avoidance is at least in the back of their minds. Maybe it isn't a huge deal for them, but man. There are VERY few instances where they actually set off the alarm. I've seen many instances where opening the door absolutely would make the most sense for the theft.... and yet they avoid doing that at almost all costs. I'd personally like my alarm to sound when glass is broken, or motion inside the car is detected.
I think about this to the point of losing sleep. I'm approaching it more as a challenging project than being angry at thieves. This is not unsolvable. It is just going to take thought, time, effort and money. And continuous refinement. I'm at half way to my goal.
I'm at the point now where *I* can't break my quarter glass with a center punch. I'm not willing to take a hammer to it just yet though... And I haven't fully treated the back window glass. And unfortunately, I can't even practically apply this treatment to the front door glass cue to clarity concerns. But I'm making incremental improvements that are going to make a difference.
