Well I am still looking and wow what a selection of cars. There are plenty of '04 and '05 cars for sale and plenty of them at small independent car lots. I even found a place in Texas called Bonham that had 10 Crossfires for sale.
One thing that I am unsure of is the model year designation, were there not models manufactured in each of the 5 years, '04 to '08? Some of the car listing sites exclude the '07 model year.
