I've done some reading since my original post, and apparently the Firepower could use the 300's hemi 8 engine, (which is now mass produced due to the success of the 300) and viper's chassis from the Dodge plant, to reduce costs, in a similar method to the X-Fire using the SLK frame to reduce costs....40K may be optimistic, but I've heard estimates of mid-high 40K's.
