Unless things have changed in the last 2 months, the 2019 won't be produced in Oshawa.

However, the current model (2018's K2's) will still be produced in 2019, and ongoing in parallel with the 2019's (T2's).
I've been trying to replace my 1998 sierra (425k) for over a year now. I had been looking for a 2-4 year old with under 80k on it and was continually shocked by how much people are asking for them. I almost bought a 2017 w/ 37k on it for 33,500 - but with truck month starting, I could buy the exact same truck 2018/0km for less 2k more. Buying used doesn't make a lot of sense given the prices on the used ones.
For that price you get v8/4x4/locking diff/double cab/trailer package/20" chromed alloy rims.
Here's GM's truck finder. The prices there are cash prices - add about 2800 if you take the financing. Those prices include everything but taxes.
