For an open convertible, the 2008 Lexus SC 430 provides reasonable safety to its occupants, according to reviews researched by TheCarConnection.com.
Neither the National Highway Traffic Safety Administration (NHTSA) nor the Insurance Institute for Highway Safety (IIHS) has tested the 2008 Lexus SC 430 for crash safety.
According to ForbesAutos, standard safety equipment includes knee-height airbags for the driver and front passenger. An occupant-detection system for the front-passenger seat keeps the airbag from deploying if the seat is empty or occupied by a child.
The 2008 Lexus SC 430 features a stability control system that helps keep the wheels from losing traction. ForbesAutos reports that, if desired, the feature can be "turned off for more aggressive handling."
Intellichoice reports additional safety equipment on the SC Lexus includes a tire pressure monitor and trunk entrapment release, in addition to a full complement of airbags. Jalopnik also reports a sophisticated braking and suspension system, the identifiers of which call to mind the "Alphabet Soup Agencies" of the Franklin D. Roosevelt Administration: anti-lock brake system (ABS), electronic brake-force distribution (EBD), brake assist, traction control (TRAC), and vehicle stability control (VSC).
Another new-yet-old safety feature (actually dating back 60 years) is the Adaptive Front Lighting System, according to Jalopnik. Autoblog reports that this is "designed to enhance driver visibility." Blind spots are not an issue with the Lexus SC 430; according to Family Car, "visibility is excellent all around with the top up or down."
Kelley Blue Book sums it up best: "the security of a coupe...the exhilaration of a convertible."
