I was finally able to get a good, clean title in my name for the stolen car. The flag on my car's VIN was temporarily removed in the system long enough for DMV to issue me a title. I overnighted the signed title and a pair of keys to the insurance company. The insurance company allowed me to keep one key, and using the original "Car 66" key fob from the Harper Woods PD will hang on my garage wall as the only keepsake I have of the car.
In terms of the replacement vehicle, we decided to have the 2012 GTCS shipped to us instead of flying to Florida and driving it back. Our schedules were just too complicated to try and schedule a trip. Plus I wasn't thrilled with the idea of a steady RPM interstate ride during the engine's break-in period. The carrier should pick up the car later this week, and deliver it to my front door by next week.
