Auto Insurance Total Loss Valuation

I am in Maryland.

My 2005 Chevrolet express AWD passenger van (106,000 miles and clean title) was totaled by someone that rear ended us. We both have allstate.

There is a big price difference between Chevrolet express passenger vans vs work vans. There is an even bigger price difference between AWD passenger vans, and passenger vans that are rear wheel drive. Work and passenger vans both come with V6s and V8 engines. AWD passenger vans are always v8 engines. I can't tell if there is a price difference between v6 and v8 engine AWD passenger vans because v6 passenger AWD vans don't exist.

I got the first valuation for my van and went through the report. The 3 comps that came back were really low, one was a v6 rear wheel drive van, the next was a v8 rear wheel drive van. Last comp was a v8 AWD van from a salvage reseller. CCC was the 3rd party valuation company that did the valuation.

I told allstate they need to make sure the comps they pull are AWD V8 passenger vans. They said they would redo the report.

They sent the second report back a week later and it had the exact same valuation. They did not take off the first 3 comps. They simply added 2 more that look like this:

2005 Chevrolet Express

Passenger 1500 135" Wb

Awd 8 5.3l Gasoline Sfi

Odometer: 106,751

Stock #: NA

Obtained Date: 09/27/2024

$ 6,500 (Recently Quoted)

Since the cheapest AWD passenger van I can find nation wide is $15K and is trashed, I called up the dealer and asked them about the valuation and where they were finding AWD passenger vans for $6,500.

The guy at the dealer told me that CCC asked them to quote at salvage title rear wheel drive van with 300,000 miles on it. That is why he quoted them $6,500. This is what they used in the comps they added.

How do I move forward with a fair valuation if these guys are doing things like this? How can I make sure I get a fair valuation for my totaled van?

Thank you
