I think the SLK suffers what I call the "Mercedes Syndrome" and the Crossfire does not. What is the Mercedes Syndrome? No matter how great your Mercedes is, it always looks like an old car as soon as their new body style comes out. Crossfires will never suffer that affliction. No one will ever say "that's one of the "old" Crossfires."
Performance? Oh, yea. That. I guess I got off topic.
