Great question. Your trade-in appraisal gives you a fair estimate based on the vehicle's condition on the day we evaluate it. If you decide to move forward with a purchase agreement, your offer is documented in the paperwork-that's your locked-in value.

If significant time passes before you buy, or if the condition of your vehicle changes (new damage, major mileage, mechanical failure), the appraisal could shift. But once we put pen to paper and you sign an agreement, your trade-in value is set. Our team is transparent about all of this-no surprises.

The best way to secure your offer? Move forward when you're ready. Have questions about how long an appraisal is valid, or want to lock in a value? Call (630) 279-5200 and we'll walk you through the details.
