Good friend just phoned from springbank airport, said that there were 3 cars that upon closer inspection turned out to be Porsche Panameras in light disguise. All 3 were dark green with front and rear bras. The drivers stopped by the airport and he had a chance to talk to them, sit in the cars and look at the engines. They were sporting 4.5L V8 twin turbos from the cayenne and had transaxles. All of them were loaded up with testing equipment and had Georgia plates.
The cars are heading North now, followed by a Nissan Xterra. Porsche has historically done their annual cold weather testing on Dempster highway, so keep your eyes open, especially you Edmontonians.
