This Lexus offers state-of-the-art technology combined with luxury. Want to make sure you're safe? The radar detects an imminent collision and takes steps to avoid it; it also sets cruise control so you stay a certain distance behind the car in front of you. Cameras in the grille, passenger side-view mirror and rear let you see everything around you.

Have trouble parallel parking? A parking assist feature uses a series of ultrasonic sensors to give you a visual representation of the distances between your car and those in the front and back of you; you get an audible warning when the preset distance is reached.

More? The chassis actually lowers for easier entry and then raises back up as you drive. A GPS navigation system with Bluetooth voice activation provides real-time traffic monitoring to help you avoid traffic jams and road closures. Bluetooth-equipped mobile phones can also be used to operate the GPS system and place hands-free calls using the stereo system. A Lexus Link option includes its own dedicated phone to place personal calls or communicate with advisers to summon help or get driving directions or concierge services.

Bored during a long drive? A 30GB hard drive stores up to 2,000 songs for the requisite mind-blowing stereo system (19 speakers), which has an auxiliary iPod/MP3/WMA port, along with CD, DVD audio and DVD video playback. A DVD rear-seat entertainment system sports a 9-inch screen and two wireless headphones.

The manufacturer's suggested retail price for all this road-ready tech is $75,705 -- for the basic vehicle. Adding all available options bumps the price up to about $89,000, and that doesn't include more than a dozen extra options that are priced individually by different dealers.
