I looked at it and came really close after a couple apps I use were added (Spotify and Overcast) until I read consistent reviews of poor touchscreen performance. I thought I'd wait a couple more generations. Then we get news that wireless connection is coming and I would vastly prefer that than to plugging in my phone every time. I'm not sure if that would require new hardware or can be done through Bluetooth in current units, but until it happens and we know for sure, I'm standing by.
In the meantime, I may be upgrading my 2012 Chevy Sonic to 2015, which supports "Hands Free Siri" which I'm pretty sure is not CarPlay proper. Seems the first Chevy to have CarPlay built in will be the 2016 Volt
