I had commerce insurance. car was totaled. I had no paper work for my mods. If you go onto autotrader, ebay, tt.net, ect. and find as many other Z's for sale similar to yours(doesnt realy have to be). Print them all up. Your basically trying to make your car seem very rare. If you cant find a car that is like yours or as in good enough shape they will compensate you for that. Try to find them alot further away from your area. Be picky Fax them to the agent. I had a red 93 tt with black leather and suede.100k miles on it. Only mods were B&B down pipe back, rps clutch and flywheel, intake and ssr rims. no receipts. I did all that shit and came out with $14000. way more than i should of got
