You have an SE Roadster, From Edmunds.com:

Unique to the base Roadster was an optional Special Edition package (2006 and '07 model years) that included Inferno Red Crystal Pearl Coat exterior paint, Dark Slate Gray cloth seats, SRT-6–style cast-aluminum wheels, a black windshield surround and satin silver door handles and side louvers. Otherwise, nothing much changed until 2008, when the base trim was dropped.
