Best place to have the exact date is too look at the bar code sticker on the engine frame right under the fuse box on the passenger side. Might need a flashlight. This sticker is the date that the engine and under carriege where connected together. The car goes out of the lime about 1 hour after and onto the parking lot. I went to Oshawa Plant in 2011 and we visited both plants. The under carriege is assembled in a different city. We where given this exact information be GM techniciens.
