I have a 2009 Cayman S ROW car that I've purchased while working overseas. Does anyone have a point of contact at PCNA or worked with them in the past on getting a letter certifying that an ROW car conforms with US specs, to enable importing to the U.S.? I assume that PCNA wouldn't issue such a letter, but wanted to see if anyone had received such a letter for a recent-year Porsche and if so, how that obtained it? Thank you greatly,
