I'm in the body shop business and you need to get a couple appraisers to put a $ amount on your Z. Make sure you have all reciepts for any thing you have done, Let the appraiser know of any difficult mods that requre extensive labor. These are nich cars and not everyone shares our love for them. I went thru this about 10 years ago when my 76 was totaled by an idiot in a Saturn. At that time I believe mine was valued over 6,000.00 just for the car. Also when this is all said and done Retain the salvage. In other word keep your car. They will not charge you much for this, generally under $500.00. You will be able to remove alot of your upgrades & bolt on's to transfer to the next Z. Second get another opinion from a different attorney. Third make sure you do not sign anything till you get this sorted out. Rick
