In most cases, your initial offer will not change ahead of your evaluation appointment. In cases where a vehicle make and model is less common, Shift may review the initial estimate and manually assess the offer as the algorithm may not have had sufficient data to offer an accurate price.
In the event a change happens, you will be notified before your appointment by a Shift Advisor. Once at the appointment, a Concierge will conduct an evaluation of your vehicle to determine your final offer.
