I just recieved a copy of the hardcover SSR book documenting the design and development of the vehicle. One chapter discusses the production of 25, 2003 Signature Series vehicles in the colour Ultraviolet. Each car has specific badging inside with the signatures of the major players involved with the development of the trucks. Were these the only genuine Signature Series vehicles produced? The reason I am asking is because a dealer up here in Ontario claims to have the first Canadian '03 SSR for sale which also contains interior badging with the signatures of Bob Lutz and Wayne Cherry and accompaning certificate of authenticity. The truck is Redline Red however. Is this particular vehicle unique? If it is, what kind of price premium would it command?
