Again, very sorry for your loss. Don't know if this is even an option for you but I had a car that was totaled and the insurance company gave me a $ number - Out of curiosity more than anything asked how much they would sell it for, they were effectively going to buy it from me.

The number was unbelievably low and I decided to do a deal with them. Have them give me the original amount for the car, less the salvage amount and I kept it.

I ended up parting out the car myself and making a good profit - once I had reached the limit selling the parts that were good, I had a junk yard pick up the car for free and hauled it off.

Knowing what you know about X5's (and having this forum available) you have some expertise and market access. That can go a long way in terms of finding buyers, understanding market $ value and potentially disassembly if you do it yourself.

Having a place away from your home to store and sell parts from is the key.

Don't know if it's an option for you and I'm sorry for your loss - it was one really nice X5.
