assuming those numbers are correct, you are still asking a question about value to the original owner only (and neglecting resale value too)
if you are asking about carbon inputs, as you lead in sentences suggest, the correct question is not how long the 1st buyer owns the car, but the life of the vehicle (and you then have to also follow the parts & sub-assemblies too)
