💬 Negotiation Script

Use these lines word-for-word with the seller. They are grounded in real data.

1.

"Based on current market data, comparable 2021 Mazda Mazda3s with similar mileage are selling around $21,000."

2.

"Given the reliability data on this car, my walk-away number is $18,900. Can you come down to that?"

3.

"I'm a cash buyer and ready to close today if we can agree on $18,900."

4.

"I'm happy to make a decision today, but only at a number that makes sense given the data."

Target price: $18,900. If the seller won't move to this range, use your walk-away number — the data supports it.
