Talk to your adjuster and tell him that you'd rather not have it totalled. Most of the time there's a certain amount of leeway involved in declaring a vehicle a total loss - letting him know that you'd rather fix it if possible could swing the decision your way. Ask if the estimate was prepared with used parts (used OEM parts are far better than aftermarket), if he was not able to find any you might be able to help out by locating some yourself (adjusters don't usually spend a lot of time searching). If you really want to keep the vehicle, see if some minor things could be omitted from the estimate that you could do yourself (antenna mast, driving lights?). You might be willing to procure the Euro headlamps for the repair and have that cost removed from the estimate also.
