This robust, standout 1990 BMW M3, originally manufactured in its home country of the United States and later modified in South River, New Jersey, showcases an impressive turbocharged S50 engine that provides a powerful 3.0-liter inline-six experience. Setting it apart from typical M3s is its Air Lift height-adjustable air suspension system and repainted Diamond Black Metallic exterior, adding a custom touch while maintaining its classic German E30 roots.
