NEW CAR IS WHAT YOU BOUGHT, NOT USED WITH BODY DAMAGE THAT'S BEEN REPAIRED! If dealer can't find you one, tell him you have but for sticker price (+) and he can cut you a check! Should be an interesting claim for the dealer to explain to his insurance company. They will not even bother, but will pay claim out of dealer funds. They f**ked up, don't accept a wrecked car, haven't you read about the problems posted on this site regarding cars that have never been wrecked? I wouldn't accept less than $10K for the BS.

PS EVERY professional tech I have seen/worked around always disconnects battery for underhood/under car repairs!
