it was my understanding he already had proof from his quote " He doesn't understand that on Carfax it shows the correct mileage (at least I think it was carfax, its one of the websites to look up the vehicles history.). " it sounded like he had already ran one...

I did read that but I wasn't sure what he was saying since it wasn't clear with the words (at least I think it was carfax, its one of the websites to look up the vehicles history.). Based off what I have tried to look up in the past I don't think it would have been CarFax.

I checked and 1972 shows 13 digits in the VIN.

Why no reports for cars manufactured before 1981?

In 1981, the 17-character Vehicle Identification Number ("VIN") became the industry standard format for auto manufacturers to distinguish individual vehicles. CARFAX uses the VIN to generate reports from the vehicle history database.

Note: There are limited sources of readily available pre-1981 vehicle history information. You may try to contact vehicle-specific clubs or groups focused on older vehicles, but CARFAX has not found any source with comprehensive data on older cars. In most cases the records simply no longer exist or are on paper or microfiche in a storage closets.

Vehicle Identification Numbers (VINs)
Every car and light truck model year 1981 or later has a unique 17-character vehicle identification number (VIN). A VIN has many important uses, including unlocking important information about a vehicle's history.
VINs also have many other important uses. For example, service shops use VINs to identify the engine, transmission and brake systems installed by manufacturers so that they can properly service vehicles. Law enforcement agencies use VINs to identify and recover stolen cars and car parts. Auto manufacturers use VINs when they resolve safety recalls.
