The best time to buy a totaled car is usually after all repairs have been completed by a certified mechanic. The car will be issued a salvage title, and you can sometimes purchase a car with a salvage title for as much as 40% lower than the fair market value for a similar car with a clean title. If you are attempting to purchase your own car after an accident, you should inform your insurance adjuster as soon as possible. You may be able to work with your insurance company during the settlement process to come to an agreement that allows you to purchase the car.
