If it's cheap enough and if it's running... not too bad... If it was a flood, there could be smelly carpets. Odd electrical failures post flood I've heard. I think an insurance company has "branded' it a total loss. Maybe you have to show receipts that it has been worked on.
You are buying a car that was totaled, reconditioned, salvaged or junked. It's up to you. If you buy a $9,000 car that was totaled, now worth $2,500 and branded as salvage, can you recondition it and end up in the black?
Branded titled cars are those that have been totaled for some reason in the past. Body damage bad enough to total a vehicle will generally seriously diminish the vehicles structural integrity. It may be less safe in another accident
