The most-registered vehicles here have the deepest local used market, which usually means more buyers when you sell and more listings to compare when you shop. Popularity is not a quality or reliability rating, and this is not advice to buy or sell any car.

Coverage: make and model counts exist only where a state publishes them for free (Washington for all vehicles; Washington and Connecticut for plug-ins; New York by make and model year). Maryland and Delaware publish fuel-type counts only. Full 50-state make and model data is sold by private vendors (for example S&P Global Mobility and Experian) and requires a paid license, so we don't show it.
