The IS 250 and IS 350 entered their second generation with a redesign for the 2006 model year. For 2007, each version adds a new X Package option that includes a sport suspension, 18-inch alloy wheels, a front lip spoiler, sport pedals, and illuminated door scuff plates. There also is a new Premium Package available on the IS 250 that adds heated and ventilated leather front seats to the all-wheel-drive version and is optional on the rear-drive model.
