Your Customers Are the Osbournes
Future-proofing technology through a retail buy back program, when sold correctly, is one step in giving consumers the confidence they need to buy something they're wary of. Smaller dealers can easily take a similar strategy. Customers will start asking for it and will appreciate the service when it's offered.
Remember, the majority of your current and potential customers are the Osbournes; they're confused and somewhat addled with all of technology choices being thrown at them. But they're also willing to play in the revolution. They just need a little help.
