Ranked by Google review rating across LLM-classified car washes in Downey, CA. Locations with fewer than 30 reviews are excluded to keep small-sample noise out of the ranking. Ties broken by review count. Dealerships, gas stations, and other auto-related businesses that don't primarily operate a car wash are excluded from the pool at the data-prep stage.
