Hyundai Tucson hybrid deal

I’m am trying to buy a 2026 Hyundai Tucson hybrid within a week or so. Trading in a Hyundai Elantra hybrid. I need help with my “yes” price.

One I found is a hybrid se white with black cloth interior. After dealer ads are removed it’s going for 32,290.

Salesmen on the real was telling me best deal in the last 90 days he’s seen on a regular se has been 10% off msrp. Invoice is 29,898 and 10% off msrp would be 29,061.

Is it too aggressive to ask for 12% off or is that even achievable? What’s a good price? How much under invoice is actually doable?
