Hi Teck-9
You could look it this from another direction , The Crossfire is based on the SLK r170 ( we all know that). So how about a skin panel swap , Did anyone see on US ebay that Xfire with a SLK(r171) front end , So i was thinking pickup a SLK 55 AMG 340bhp (panel damaged), You already have a Xfire , to me that would be a nice project if you are set on the Xfire look but neeeeed more speed & that V8 sound . You can get a SC for the 55 AMG & this will get to 500BHP + you have all the corect running gear (brakes / trans ect ). I know, i have the 55 AMG at the moment & the different from the 3.2 Xfire is very very nice

. If they would have carried on with the Xfire & produced Xfire2 based on the R171 SLK i just hope this would have been in the line up
Cheers
Andy
