Dr. Darwin: what kind of estimate are you getting? I'm curious to know if the window would be too thick as a mod.

Without going into too many details, if you are planning on adding armored windows only, I would not recomend so. The glass is much thicker than standard so a lot of fitting is done. The interior is modified to fit the ballistic glass and even the hinges on the doors are changed in order to carry the extra weight without sagging.

Regarding an estimate on the cost. Without having the exacte price, you can more or less expect to pay double the basic X5.
The whole car is stripped down, and armoring is added throughout the vehicle.
One of the more expensive items is the windshield, which on some vehicles can cost in excess of $6000.

do you have a legitimate need for armoring?

Are you looking for protection for just small arms fire or something that can withstand rpg or IED attacts ?

what do you mean legitimate? (no i just want to drop $30k, just dont know where,lol)...

lakai, yes just small arms fire, nothing too big, you really cant go any bigger on a X5 to be honest....

If you want to save on weight, theres a method where you could go with thinner steel plates and kevlar. Kind of like bullet proof vests on top of the steel

Or move to another neighborhood. That's got to be less than $50k.

BMW has a security version out. i've seen a thread here of it before. I don't know how the adaptive drive is configured on that though..
