I read Consumer Reports as well, and usually follow their recommendations. They do not recommend any Crossfire or the SLK siblings. Actually, no Mercedes cars are recommended and very few Chryslers are.
I still wonder if I made the right choice with this SRT6. The complexity/rarity of this car really worries me.
Since it won't be driven much, I wasn't too worried about CR's complaints. However, if I was looking for a roadster to drive daily or close to, the 350z would have been my choice.
