Is this a good deal?

Looking at buying a new 2026 Limited Trim 4WD Tundra (gas only/non hybrid). I've spec'd out what I want on that Trim, the addons/upgrades that I really care about (my must haves) amount to roughly 3500 or so.

Based on some research here on Reddit the consensus back of the envelope math seems to be roughly take 11% off the TSRP (Trim base price+options+delivery,processing,handling fee), account for 3K consumer cash back, and then add your TTL on top. That math would land me at right about $57K OTD price.

Of course in the real world, there are gonna be many more options already loaded on the truck that I don't really care about but can't exactly "uninstall" - for example $1350 for panoramic roof. So if I want that vehicle, I'm gonna have to come up from my original figure.

I've found one that has everything I want, except one thing: Catalytic Converter Shield (priced as a 579 option from Toyota).

They've come back with 61K OTD as it is. I want a lower price including the catalytic converter shield. Am I crazy? What's a good price for this one?
