Are the cars listed on OffLot real?

Not during the preview. The listings on OffLot are simulated to show how the shopping experience works, so the VINs, prices, dealers and vehicle histories should not be treated as real vehicles for sale. The model information, buying guides and education articles in the research center are meant to be genuinely useful, but if you want a specific car today, verify it directly with a dealer and check the VIN yourself.
