Lexus's midsize luxury sport sedan, similar to the BMW 5 series, the Mercedes E class, the Audi A6, and the Infiniti M sedan. The GS was redesigned for the 2006 model year, adding an awd model (available only with the V6 engine) to the lineup. The 2006 GS was one of Lexus's first vehicles to carry the company's new "L-finesse" design concept, a theme that seeks to intensify their vehicles' styling while keeping them relatively conservative, refined, and quite elegant. The new (06) IS and the 2007 LS and ES both have "L-finesse" styling also.
The GS is a fast, fun car with loads of safety features and luxury. The mark levinson 14-speaker surround sound system in my 06 GS 300 awd is amazing. This car is well worth the price, especially given the Lexus/Toyota reputation for reliability. And fuel efficiency.
Lexus came out with a GS hybrid model for 2007, the GS 450h. Other models for '07 are the (V6) GS 350 and 350 awd, and the (V8) GS 430. In '06 models included the (V6) GS 300 and 300 awd, and the same (V8) GS 430.
The waiting list is long for a GS. I'd be surprised to find one in a Lexus showroom.
I just bought a Lexus GS 450h hybrid. Jesus this car is fast!
