Yeah, the rumor is that it will be green, like the one pictured on the 2008 brochure (accessory brochure maybe?).
The base on the 2008 RS 5.0 was $18500, gold paint, upgraded fabric, sun roof, and Kenstyle body kit. Some dealers added fog lights, lowering springs, front and rear struts, and the navigation system - that brought the price up to about $22,000.
