Performance rules the day with the Lexus GS460, thanks to a 4.6L 8-speed transmission producing 342 hp and the highest top-speed of the GS line. In 2010, Lexus refreshed the GS460's style for a new age, and these improvements, along with a host of those left unmentioned, place it among the most luxurious mid-size sedans on the market. Now that you own one, don't make just any addition or upgrade. Choose from the custom-fit parts and accessories listed below. It would be a shame to let anything generic so much as smell your Lexus GS460.
