GM press release :
DETROIT – A special edition of the 2011 Chevrolet Camaro Convertible will be showcased in the annual Neiman Marcus “Christmas Book,” the luxury retailer announced today.
Only 100 special edition convertibles will be built, each offering luxury appointments inspired by Neiman Marcus combined with the legendary performance of the Camaro SS.  This is the 84th edition of the luxury retailer’s catalog of ultimate holiday gifts. Neiman Marcus debuted the Christmas Book and the special edition Camaro Convertible today at its flagship store in Dallas.
“Neiman Marcus provides a great platform to showcase the new Camaro Convertible,” said Tom Peters, Chevrolet Design director. “And, it enabled us to create a special edition car that combines the powerful design and performance of the new Camaro with an element of exclusivity, craftsmanship and customized luxury.”
The Neiman Marcus Edition is defined by its exclusive Deep Bordeaux exterior color, accented by subtle, “ghosted” rally stripes.
“The tri-coat, metallic paint shifts in response to natural light,” said Peters. “In low light, it appears almost black with a touch of deep violet. In sunlight, a little bit of red and burgundy appear.”
The Deep Bordeaux color is complemented by a color-matched fabric top and windshield frame finished in matte silver, both also exclusive to the Neiman Marcus edition.
The interior of the Neiman Marcus Edition Camaro Convertible features exclusive leather interior appointments, including amber-colored leather seating surfaces offset by black leather side panels and red stitching. Red accents also appear on the center console, steering wheel and shift knob. The Deep Bordeaux color from the exterior is brought inside the car, appearing on the dash and door panels.
The Neiman Marcus Camaro Convertible has a retail price of $75,000, and will be ready for delivery in the spring of 2011. Reservations for one of these limited-edition cars will be accepted beginning at noon, EDT, on October 19, 2010. To place a reservation, customers can call 1.877.662.6276.
