Celebrating their 10th year in the United States in 2004, Kia's brand identity is undergoing a massive shift towards being more than a manufacturer known for cheap vehicles. The 2004 Kia Amanti is an attempt by the South Korean auto company to better define itself as a builder of premium vehicles. The large, new flagship sedan in the Kia line-up is heavily equipped with standard features such as dual-zone climate control, power front seats and four-wheel disc brakes with anti-lock control. The 2004 Kia Sorento sport utility vehicle can now operate through a five-speed manual transmission. The Optima and Sedona have modified grilles for 2004 featuring the Kia badge. The Optima also receives larger diameter wheels as standard equipment representing the second time in three years the standard wheel size is enlarged on the mid-sized sedan. Alloy wheels are now standard equipment on the 2004 Kia Rio Cinco wagon.
