Chevrolet is enacting a strict policy to ensure buyers of its 2025 Corvette ZR1 don't flip their cars for an easy payday. The company is requiring every new owner to sign a retention letter asking them to keep the car for at least one year. If they decide to sell before then, they'll be barred from buying in-demand Chevys for the foreseeable future. They'll also void the car's factory warranty.
