The Solstice is more a direct Miata or now defunct MR2 competitor. Its really in a different class than the Crossfire. That's like people who compare the XF to a Mustang... Aside from that, I saw a Solstice at a car show this past weekend and think Pontiac may have potential to steal some Miata sales away, but I'll always think the Miata is a better car. Once they get a few on the road and on the autocross tracks we'll see.
And what does the Eclipse have to do with anything? Its already been recalled by Mitsu for problems. I'm not a fan of it either.
