I bought my '68 coupe from a car dealership in Des Moines, IA. I know the name of the person that had sold it to the car dealership.
I also have the Marti Report, which reads the dealer number and the name "Rabenbergs INC" in Selby, SD. But after a brief google search I found out this was not a dealer, more a farming company. Could this be their side business? Or is it the name of the first customer - in this case was it a company car?
I live in Europe, have no possibility to visit the DMVs, even if they could provide me with any info. Is there any way to learn how many owners did the car have? Where was it registered and maybe some pictures from the past times?
