Hey. Thanks for clarification and the findings.Yes. I'm sorry it was not clear. 1530246 was/is on the list of GTAm here: GTAm chassisnumbers
If I understand, 1530246 has been identified as a "potential typo". I think the for sale ad I posted makes it clear that this chassis number needs to be removed once and for all. There should be no question - it is not, and never was a GTAm.
