Here's an update!
So after dealing with a bunch of dealers, seems like there were no 2020 Stinger's really left, all of them turned out to be demo's with 5000+ km (one even being 12000 km). Orangeville Kia told me from the beginning that they can't possibly get me a 2020 model and I appreciate them so much for that. What you all said about Orangeville Kia was 100% accurate. They get straight to the point. Scott offered me $2250 off MSRP for a 2021 which is not bad for 84 months 1.99% or 60 months 0.99%, compared to the measly $2000 off I was getting for a 2020 demo with 12000km on it....
At the time, I work from home (Covid

) so there isn't a rush to get the last stock of stingers anymore. I told Scott about the situation and he said I could reach out to him any time essentially. Looking forward to making that purchase in the next couple months, hopefully.
I also recommend Orangeville Kia as they seem to be offering the best prices.
