Help!! Insurance company trying to screw me!!

[Craftsman729]

If anyone can help me out here, that would be most appreciated. My brother's 1996 Subaru Impreza LX was hit by a deer a week or so ago. Now the insurance company has totaled it and will only give him $4600 for it. It only had 74K on it and all the options. We found a similar one on cars.com that sold for around $8500, but the insurance company won't honor that price because "it has to be in the for sale state when the insurance company calls about the vehicle". Does anyone have a similar impreza for sale or know of someone that does that would be willing to help me out here? Trying to get my bro more money for his totaled car so that he can afford a replacement vehicle. Any help would me most appreciated!!
