Buying a used car can feel like a negotiation marathon—and what you say can cost you thousands. Salespeople are trained to pick up on small comments that reveal your budget, credit score, or emotional attachment to a car. Even innocent chatter like “I love this color” or “I need a car today” can flip the power dynamic instantly. The goal isn’t to be cold—it’s to be strategic. Here are 10 phrases you should never say to a used car salesman, and what to say instead.
1. “I Really Need a Car Right Away”
This signals desperation—and desperation kills negotiation power. The moment a salesman knows you’re in a rush, they know you’ll pay more. Instead, act like you’re comparing multiple options and have time to think. Say, “I’m exploring a few vehicles this week before deciding.” That shifts the balance and puts pressure on them to make a stronger offer.
2. “I Can Pay $400 a Month”
Monthly payment talk is the dealership’s favorite trap. They can easily stretch your loan term to hit that number—without lowering the real price. Focus only on the total purchase price, not what you’ll pay monthly. Once the final figure is set, then discuss financing. A shorter-term loan at a fair price always beats a long, inflated one that just “fits” your budget.
3. “I Have a Trade-In” (Until After You Agree on a Price)
Mentioning your trade-in early gives the dealership more control. They can inflate your trade-in value while overpricing the new car—or lowball both. Negotiate the car price first, then discuss the trade-in separately. Treat them as two distinct deals, and you’ll see the real numbers. Transparency starts with separation.
4. “My Credit Isn’t Great”
Be honest when financing, but don’t volunteer that information upfront. Telling a salesman your credit is bad lets them steer you toward higher-interest loans or unnecessary add-ons. Instead, apply for pre-approval with your own bank or credit union before visiting. Walking in with financing already secured shows confidence—and often gets you better offers.
5. “What’s the Lowest You Can Go?”
This sounds like a negotiation move, but it rarely works. It signals you’re ready to buy if they shave off a token amount, so they’ll drop the price minimally. Instead, say, “I’ve seen similar models listed for around $___—can you match or beat that?” It anchors the conversation around market data, not emotion. You’ll seem informed, not impulsive.
6. “I Love This Car!”
The more you gush, the less room you leave for a fair deal. Salespeople are trained to latch onto enthusiasm and use it to justify holding firm on price. Even if you’ve found your dream car, keep your poker face. Try something neutral like, “It has a lot of what I’m looking for.” Save your excitement for after the paperwork is signed.
7. “I’m Paying Cash” (Too Early in the Conversation)
You might think cash gives you leverage—but dealers often earn more through financing kickbacks. If you say you’re paying cash before negotiating, they may become less flexible. Negotiate as if you’ll finance, agree on the lowest out-the-door price, then reveal your cash payment. It’s the simplest way to maximize your deal.
8. “The Internet Price Is the Lowest, Right?”
Dealerships often list teaser prices online to get you through the door. Those listings may exclude destination fees, documentation charges, or required add-ons. Never assume the online price is final. Instead, ask, “What’s the out-the-door price, including taxes and fees?” It’s the only number that matters—and prevents nasty surprises in the finance office.
9. “I Don’t Know Much About Cars”
Even if it’s true, don’t say it. Salespeople hear that as an open invitation to push extras or skip details. Instead, do a little research before you go—review model reliability, fair market value, and common maintenance issues. When you speak confidently, the conversation shifts from persuasion to partnership. Knowledge is your invisible armor.
10. “My Budget Is $20,000”
Always make them show you their best price first. Once you reveal your budget, they’ll find a way to hit it—even if the car’s real value is far lower. When asked what you can afford, respond with, “It depends on the vehicle and total out-the-door cost.” That keeps negotiation open-ended and prevents them from anchoring you at the top of your range.
Smart Buyers Talk Less—and Ask Better Questions
When buying a used car, silence is a powerful tool. Every detail you share gives the salesman data to work against you. Ask direct questions, avoid revealing too much too soon, and always focus on the total price—not monthly payments. The best negotiators aren’t the loudest—they’re the calmest, most informed, and least predictable in the room.
