Many factors affect the value of a rebuilt classic car including the car's manufacturer, mileage and remaining original equipment. Other factors that may affect the value of a rebuilt car include its age and condition.
A car's manufacturer plays a major role in its value no matter the age. Car makes such as Rolls-Royce, Aston Martin, Jaguar and Porsche are automatically worth more than more common brands, such as Dodge or Chevrolet, even if they have been rebuilt, notes CarsDirect.com.
A car may also lose value if it has a lot of miles on the odometer. Mileage is a primary factor in determining a car's worth, so the fewer miles a car has, the more it is likely to be worth.
When rebuilding a car, it is important to use as much of the original equipment as possible. This original equipment includes the interior parts such as the dash, carpet and pedals.
A car's authenticity also plays a large part in its value. The car must have the original vehicle identification number, date code and casting number to retain its value.
A rebuilt car can also have its value raised or lowered depending on its color. This is especially true for muscle and sports cars. A classic sports car painted red is generally worth more than one painted brown, states CarsDirect.com.
