Does that price leave any room for negotiation? It seems Chrysler would work with you - they should know that a dealer won't give them anything for the car and they will be stuck with it. Maybe somebody here has experience in this...
BTW - I owned a 1969 Mustang convertible 302 with FMX tranny black top over Meadowlark Yellow. My favorite year - I love the way the headlights look. You can not mistake a 1969 model. And you can not mistake your SRT-6 for any other model as well.
