http://www.channel4.com/4car/road-te...05-/gs05-.html
Summary:
Assets
High-tech safety kit, refinement, hybrid option, Lexus reliability and quality, handsome looks
Drawbacks
No diesel option, hard ride, poor steering feel, lack of character; VDIM and pre-crash safety systems only in GS430 model
Verdict
It's not quite the all-out sports saloon Lexus claims it to be, but it's a comfortable, sophisticated, high-quality choice with some unique touches
