I would honestly recommend getting a good used C7. You'll be able to get a Z51 or a car with a higher trim level and still save some money over a brand new one. I had my 2014 Z51 3LT for $50k (plus you'd pay PST). I totally understand wanting a new car when you're buying your dream car, but look around. I think the prices on the used C7's are a helluva steal. From my research you don't pay the GST on private used sales, just the PST.
