Really this is a great car. I have never owned a Toyota or Lexus but it is really a great car. We bought this car with 44,000 miles on it and Lexus has taken care of all of our concerns to this point. They replaced the tires, battery, full brake job and vanity. Drove a 900 mile plus road trip at an average of 81 and got 28.2 mpg. There is no sound in the cabin except the engine when you unleash the little monster within. The G35 exhaust was annoying after a while and we definitely enjoy the comfort and class our RWD IS250 brings. We will always own a Lexus because of how much we have enjoyed our first so far.
The NAV system, chrome wheels,HID lights that turn where you turn, paddle shifters and the sound system.
