The insurance adjuster finally (really it is only been 2 business days) looked at the car today.

Yup, it is totaled.
They said that there was about $5,200 in damage for what he could see, and that didn't include anything with the tranny and the tranny was definitely leaking after the accident.

They offered for me to buy it back for just $1000 which is a heck of a deal, however it would be a bit risky to fix it if the transmission is damaged and needs to be rebuilt/replaced. So then I thought that maybe I would buy it back and strip it down. I could get my $1000 pretty easily.

My problem is that we have been trying to sell our house (near Des Moines, Iowa) which is 2 hours away from where we live during the week (Cedar Rapids, Iowa), so we are just in an apartment until the house sells. I know of nobody that has the space close enough to me for me to work on it one way or another.

It really sucks to be honest.

I can't find a 2000 GTP with around 75,000 miles anywhere out there (my car has 74,600 miles) for anywhere near the price that insurance is willing to give me (NADA dealer book value). They didn't care about the upgrades, or the expensive tires, or that it has been perfectly maintained.

It is interesting that if they keep the car, it goes to auction and becomes a salvaged title car... If I buy it from them, it stays with a clean title, and since it is over 10 years old, in Iowa I wouldn't even have to disclose that it was ever in an accident. And it was the insurance adjuster that told me this!
