I am looking for an early to mid 70's 124 Spider. I have found a 1976 but cannot get any information from the 13 digit vin #. All the sites says its incorrect because it needs 17 characters. Can you convert a 13 digit to a 17 digit VIN and find history or is it because the sites do not go back that far? Trying to also find a car that belonged to my wife's grandmother back in the mid 80's. I am assuming it also will have a 13 digit VIN. What's the best resource to find a specific car? Should have the vin this week.
