That's decent, though not overly impressive at this point. A victory of sorts for GM, but with the available choices in todays market this isn't anything groundbreaking.
Unfortunately GM had the habit of being a good 5 years behind the curve for this segments demand.
Domestic automakers seem to be making some better decisions and rebounding from 20 years of mediocre (at best) product. Only time will tell if they continue with good decisions and if their product will stand the test of time.
The sky seems to be a good car so far, though is still a few years away from proving anything besides numbers. As many sources cite the sky is powerful but is not nearly as refined as it's competitors. The interior is the most prolific under-achievement of all GM automobiles, it is simply unimpressive, lower quality and overpriced. This has been a constant with GM vehicles and seems to be one of the last things they want to address. They arn't going to steal an incredible amount of customers away from their competitors with this approach. The GM fit and finish is simply not as good as it's competitors. What's even worse is that the price point, which was a HUGE selling point for the sky and solstice, went from a super deal to a mediocre deal by the time they were released.
I'm still a good 5-10 years away from considering purchasing a domestic auto. Warranty is really a non-point when it comes to purchasing a car, it's not even on my list at all. I'd like to see GM get their act together in the next 5 years or so, then I can consider purchasing a car from them expecting a truely quality product.
