I own an IS 250 with some extras. I got the larger wheels and the upgraded interior but without the nav (I know my way around town, thank you very much). I get more looks in this car that my buddy in a Porsche. This is a truly beautiful car and it has top notch quality. Power, luxury, style and name brand all in a great price range with everything! You cannot beat this with a stick. This kills the BMW 3, Infiniti M3 and the Audi A4. I drove them all and this car was hands above them all in nearly all aspects. Great job on the IS Lexus guys!
Leather seats are so buttery you will want to eat them. Silent while driving. Overall looks are a killer. Power plus. Paddle shifters are a hoot!
Interior room. I am a small guy and my family is on the small side so we all fit just fine. I feel a little sorry for a larger family... may be a bit cramped.
