Skys and Solstices are EVERYWHERE in this neck of the woods. There are even two Sky Turbos at work.
Have only ran across one of these that could tackle the SRT6. Last year at Woodward, a guy was tooling around in a Mallet Solstice:

IMO, the Sky is better looking than the Solstice, but the top design on both is really poor. You must get out of the car, open the trunk, fold the top down manually and do the reverse to get the top closed. There are a lot of top 'fitment' issues with them as well.
No doubt the turbos are fun cars. I just can't see paying that much for a car with the same engine as the Cobalt SS.
If I hadn't got the SRT6, I might have probably purchased a Honda s2000.
