He is asking about the invoice price, not MSRP.
An SLT2 is about $35K USD MSRP, so invoice would be around $31k, the SLE2 I would expect to be more like $29K, unless youre also looking for AWD.
The invoice price on my 2LT (like a SLT 2 options wise) with leather and power liftgate, FWD and 4 cylinder was $26,800 USD. So I would still think an SLE2 Terrain should only be about 29k invoice with no leather or power liftgate, but the V6 option and the wheels.
Invoice is what the dealer pays, not what they mark them up to. Right now the CAD is worth more than the USD as well. Does GM jack up the price to Canadian dealers? Would see odd seeing as how much of GMs stuff is made in Canada.
