In most of its guises, the 2011 Lexus IS isn't especially opulent, however. Even with the optional wood trim packages, the IS family feels at times too much like the dressed-up version of a less-expensive car inside. Enforcing that impression is quite a bit of tire thrum from coarse surfaces and a fair amount of wind noise at higher speeds, even though the powertrains remain smooth and isolated.
Interior space is also quite limited. Though the front seats are roomy and well-padded, headroom borders on tight in front, while the rear seats are cramped and short on headroom and legroom both. Don't plan on having adults ride back there—even across town—if you want to keep business relationships.
