First let me thank everyone for responding.
So this is the update:
I went into the Hyundai dealer with the $6K over book value offer letter. The Used Car Manager came outside and looked at my 2019 Hyundai Kona (12K miles) and in Excellent condition. I was thinking: "this is going to be easy".
And then...
$25K offer. WTF!
So he says: "Oh that letter is just from a marketing company we use, and we can't honor that"
"We can't sell that car for more than $28K".
I said to the guy: "Well that's a great way to gain my trust in your dealership". So then he said, "Maybe if I talk to my manager I can get it to $25.5", which is total BS. He knows what he can buy it for. Like he's doing me a big favor.
That's nothing special, and I'm not in any rush to sell the car at $25K or $25.5K.
If I do want to buy another car. Like maybe that 2023 Chevy Bolt EUV, and I don't do a private sale, I could probably get $25.5 right at Chevy. I don't need to first sell it to Hyundai.
So for now I'm just keeping the Kona. It works great, and it has a brand new battery thanks to a recall.
Thanks again,
If anything changes, I'll post here again,
