2019 Toyota Sienna

Thoughts on negotiating (down obviously) the price on a 2019 Toyota Sienna XLE Premiun AWD with no listed damage and clear carfax. 145,000 miles listed at $20,000. Been on the lot for 3-4 months, just had a price cut from 22 to 20. I’m sure they have no margin at this point but I seriously feel like this should be in the $17,000 range and where I would go after buying this.

Maybe I’m wrong I haven’t bought a car in a few years. What are y’all thoughts?
