Looking for an 05 or 06 Murcie Roadster

I am looking for a decent mileage, (under 12K) Murcie roadster. Black, Blue, Yellow or Red..with no paintwork, etc.... Not willing to pay full retail, but willing to pay more than wholesale. looking to trade my immaculate 2004 Ferrari 360 Spider Red/Tan, F-1, 8800 miles, 430 wheels, daytona's, hifi, shields, ferrari racing exhaust, carbon fiber Airbox covers (carbonio) and carbon fiber rear louvers, shields, front challenge grill, custom mats, hard wired battery tender, not a nick or scratch. Owned since 2007, original owner was a principal in Champion Motor Group on Long Island. Major service done 3 years ago about 1,500 miles ago, and yearly fluid changes since. All 3 remotes (2 black, 1 red), 2 keys, all books, tools,etc.... What should I be getting for mine, and what should I be paying for the Murcie?
