Here's what the Nationwide Insurance site says:
"Want to keep your totaled car?
After your auto insurance company gives you the check for the totaled car value, it owns the vehicle. Oftentimes, the vehicle will be sold at auction usually for parts with proceeds going to the insurance company.
But you also may keep the totaled car. Just inform your insurance company as soon as possible. If you wait too long and it goes to auction, it's difficult to get the vehicle back. And in most states, youll need an auto salvagers license to attend the auction and bid on your car.
If you choose to keep the vehicle, your auto insurance company will still reimburse you for its actual cash value, less your deductible. The company also may deduct the amount it may have received if the totaled car was sold at auction.
Now that your car has escaped the auction block, youre responsible for having it repaired to safe driving condition, including any work required to pass inspections.
Once your formerly totaled car is fixed, getting new liability insurance coverage shouldn't be a problem as long as the passes inspection. Getting other types of coverage, however, may be, so youll need to talk to your insurance professional.
Finally, you also may need to buy a salvage title for your car. "

Liability is what I got after I got my totaled car fixed. Your insurance agent should be able to guide you in whether this is an option for you, should your car be totalled out. You can also negotiate how much the insurance company gives you for your car if you have anything like expensive rims, recent engine or transmission work, etc.
