I am 99% sure they started building on February 16, i sent emails to the cobalt marketing team everyday for seven days before a guy finally emailed me bac and gave some info on my car and iun the e-mail he told me that production started on the 16. My car was built on Feb. 22. I have the build manifest that comes in the trunk of the car and it even has the time started on it (07:32) Kinda neat I have sent two emails so far to the same guy and no response as of yet. If i get one i will let you know.mken said:I was wondering the same thing, I know mine has a Feb. build date. Isn't Feb. the first month they started to build them?
