I get the opinion that MB is not happy about making the Xfire - a car better looking than theirs for $10k less money. I understand too that production of the Xfire may be questionable beyond 2006 or 2007. I imagine much depends on how much it earns for DC.
Have you seen pictures of the SLK350? Yuk!!! If MB was smart, they'd put their badge on the Xfire.
