as-new car; pre-registered car; ex-demo car
Refers to a car that is sold as used but is in near-new condition, often with very low mileage. Common in the Japanese used-car market for vehicles that were registered by a dealer for demonstration or inventory purposes, or barely driven before resale.
You can often buy a pre-registered car much cheaper than a brand-new one.
This dealership carries many low-mileage ex-demo cars.
Compound of 新 (new) + 古 (old) + 車 (car), literally 'new-old car'. The term reflects the car's dual nature: it is technically used (古) but in like-new condition (新).
