with a 40 year old car how do you prove if it has 40,000 or 340,000 , if I am looking at a 40 year old car I look at the present condition Not the indicated milage , you could buy a 40 year old car that was wrapped around a tree & left outside to rot for 38 years with that still has less than 20,000 original miles or a car like 4 cs that could have been babied for 40 years & have 300,000+ miles on it [ not that I am suggesting 4Cs Cuda has that milage on it ]
