The LP400 was the first Lamborghini Countach available to the public. First unveiled at the 1971 Geneva Motor Show, the LP400 was in development for three years before finally hitting the road in 1974. Boasting it's now legendary Marcello Gandini designed body, the Countach was a styling revolution, heralding a design language that is carried into the present day. Powered by Lamborghini's well established 4L V12, the LP400 offered 370hp running through a 5 speed manual transmission to the rear wheels. These early production Countachs are the most faithful to Gandini's original design, with minimal deviation from the prototype. The LP400 is notable for being equipped with a periscope-like system in order to improve rearward visibility. This periscope system was only available on the LP400, with later models fitted with a more traditional rear view mirrors. As such, it is common to see these early Countachs labeled as "periscopios." With only 157 examples of the LP400 produced, it is by far the rarest variant of the Countach. This rarity, coupled with its faithfulness to the original design, means that an original LP400 is a true collectors dream, with current market values reflecting this desirability. Production of the LP400 ended in 1978, and it was replaced by the Countach LP400 S.
