It provided a much needed model to slot between the ES and LS models. Lexus GS300 parts are luxurious and high quality. The second generation was styled in Japan and offered quad headlight setup. The GS300 was one of the last cars beside BMW to offer and inline 6 engine though the third generation GS300 had a V6 engine. The GS was redesigned on later years but has stayed remarkable true to the styling and size of the original car. The range was steadily expanded with different engines.
