Crossfire fitted with a 6.1 L SRT V8 engine, you will need LOADS of money though!
Below is a link to a brochure page for the Startech Crossfire -
http://www.startech.de/Flyer_CHRYSLER_Crossfire.pdf - click on the
"
Catalogue CHRYSLER Crossfire" - image, reduce the PDF file to 100% and go down to page 3.
This has got to be the ultimate Crossfire if you like speed.
