A "Rebuilt Title" is a designation given to a vehicle that was previously declared a total loss by an insurance company but has since been repaired and restored to a roadworthy condition. This title indicates that the car has undergone significant repairs and has passed inspections to ensure it meets safety and operational standards. Vehicles with a rebuilt title often sell for less than similar cars with clean titles due to their history of damage. Buyers should be cautious and conduct thorough research, including checking the vehicle's history report, to understand the extent of previous damage and repairs before making a purchase.
