I would dispute that. When I bought my 1999, I stopped into the big local Dealer here in Monmouth county and asked the Service Rep if he had ever serviced this VIN number. Sure enough, it was serviced there since new and he read me the major items that had been replaced recently. Very helpful in charting out my Maintenance Plan. He wouldn't tell me the previous owner's name, but I had that already. The Service Rep may have been phishing for some of my business, and I did nothing to make him think otherwise.
The previous Owner has no right to privacy in this situation, once he traded the car in......what ever I could find out was a matter of public record.
