I assume you're located in the US and are picking up your RS under the PCNA Euro delivery program.
I'm picking up my GT3 at the end of June and Porsche has accepted USAA to provide for the balance of the insurance that I need for the 6 months that I will keep the car there. USAA is able to underwrite insurance in Germany.
If you're picking up the car towards the end of June, there are about 5-6 US rennlisters doing the same. Feel free to join us.
Rennlist Euro Meet waiting for PDK: Under new PCNA rules, the car has to be exported to the US within 6 months (used to be 12 months). Under the PCNA European delivery program you pay a rather healthy deposit to cover the VAT payment, which they will refund with interest once the car is registered in the US.
