This is for anyone interested in the outcome of the request for information through the RMS
So I got my response letter today.
My questions were : date first registered, place of sale (dealer), has it ever been out of rego. Also if they could clarify if the car was transferred within the family (as the owners said they bought it new but showed up as transferred specifically stating I didn't want details just a yes or no from what they could see)
The response.
Information relating to the vehicle regarding date first registered, original number plate, place of sale was NOT located. Therefore decided that this information is not held by the agency.
Information relating to the previous operators transfer is also not held by this company.
Then 2 pages further into all the democratic nonsense this
DRIVES indicates that the vehicle was first registered on the 01-01-1972 to MR ********. In addition our records indicate it was transferred between MR & MRS ******** on the 09-02-1993
All records prior to 1988/89 are not able to be verified as the original documents and microfilms have been destroyed and no longer exist as a result inaccuracies in the exact dates my be present.
The vehicle history check does state that the car was first registered in Feb 1972. And according to the RTA when I asked at the desk yes it's still the same plates, never been replaced, and never been out of rego. So it seems their computers don't talk to each other. So I guess I'm as close as I'm going to be without the log books.
