IS 350 might be the most economical luxury sedan sports car on the market, but it is also the fastest. Seriously, to get faster than this car, you have to buy a Corvette, a Viper, or a 911 turbo. This car cranks. The luxury package is a must, with a TALKING map navigation (named "Lexy"), keyless pushbutton starting (your key never leaves your pocket for any reason), parking camera, easy sunroof operation. The map alone is worth the extra $5k it costs.
Keyless entry to car and trunk. Keyless ignition. Navigation system rocks.
Add the following for a 10 rating. 1) needs a stick shift option instead of the "tiptronics"-like option. 2) tall drivers heads brush the roof: driver's seat needs ability to go DOWN more, closer to the floor. 3) XM radio should be part of luxury package. 4) nav system needs "show TRAFFIC" option.
