I'm not aware of any. When I had my Cobalt the Cobalt/Ecotec club was very active. However, since I bought my HHR SS I haven't contacted them to see if they are still around. If you hear of anything, please post it!
Hey Crazy Car Kid,
Come on down. We are having weather you would enjoy.
Today the high was around 20 deg.(at midnight) and is going to -9 tonight.
On Tues. get your swim suit as it will be a nice -2 for the high and Wed. morning it will be -18 or so, and you get the wind chill for free!!!
See just like MI.
