Trade-in value email sent to owners of a three-year-old model

Pull a list of customers who bought a vehicle from you about three years ago and email them an estimated trade-in range based on current demand for that model, along with an invitation to bring it in for a firm appraisal. Mention that appraisals take about 30 minutes and require no appointment.

Why it works: Three years is when many loans and leases approach a natural transition point, so reaching owners at that mark catches them while they're likely already considering a change.
