I went to a garage sale a few weeks ago and ended up buying two Honda minibikes , one with zero miles, still in the original shipping crate, the other ridden only once around the backyard, showing 0.9km. Both are 1970 models, 32 years old. And I know that some musclecars have been found with very low mileage. Never say never.
