Feature content nearly the same between the 2010 Lexus IS 250C and IS 350C, but between the IS C and the standard IS sedan lineup, there are some key differences meant to keep convertible living as easy as possible. The audio system adjusts its volume up when the top is down, and the fan cranks up automatically to supply more air. The IS C also comes standard with an eight-speaker audio system with six-disc changer, satellite radio, and a USB interface.
Lexus makes plenty of high-tech options available, such as Intuitive Park Assist, Adaptive Front Lighting with bi-xenon headlamps, and a voice-activated navigation system. Both the sound system and the climate control system automatically change their operation depending on whether the top is up or down. A Luxury Package adds rain-sensing wipers, HID adaptive front lighting (which now for 2011 are packaged together with LED running lamps), semi-aniline leather, and heated/ventilated seats with memory.
In addition to the factory options, a new line of F Sport dealer-installed accessories is offered on the IS C. There, for a somewhat high price, buyers can spice up the IS C's appearance with wheel upgrades and special trims, add a more vocal exhaust, or upgrade the suspension and brakes.
For 2011, there are a few new exterior colors on offer, and the interior gets new black metallic and silver trims.
