Our appraisers use a multi-step approach: we start with industry market data based on your vehicle's year, make, model, mileage, and body style. Then we adjust for condition (interior, exterior, mechanical), service history, accident history, and local demand. A test drive lets us assess how the engine, transmission, and systems are running. We look at wear patterns, maintenance records, and any needed repairs. All of these factors come together to determine fair, competitive value. We're proud to be transparent throughout the process-there's no mystery. When you bring your vehicle in or call (630) 864-6683, our team will be happy to explain exactly what we're seeing and why we've arrived at the appraised value.
