Buying a car with a salvage title is not always a bad idea especially if you can buy the car outright and just want a cheap vehicle to drive.
You can still easily insure the car with liability auto insurance through most any auto insurance company but it may be hard to get financing for a vehicle that has a salvage title.
Also having a salvage title lowers the value of the vehicle so it can be hard to sell the car in the future but if you don't plan to trade the vehicle in or sell it then having a salvage title is not always bad.
