A dealer told me the Toyota Sienna "can't be negotiated." So I called 7 of them across the Pacific Northwest on a 2026 Sienna XLE. I break down exactly how I went from $6,500 above MSRP on the first call to $2,000 below MSRP on the last one — an $8,500 difference. You'll hear every markup justification, every "that's just market value" deflection, and the exact moment dealers start competing against each other for the business. If you've ever been told a hot car has no deals, this is exactly how you prove them wrong.
