Overall this car has met or exceeded my expectations. I have been loyal to Lexus having 2 GS 430s in last 6 years but wanted more performance type numbers and feel. Magically, the IS-F was born. It is very unLexus in its stiffness and ride but what I was expecting in a true performance sedan. It still has many of the nice Lexus features and luxury components. However, this is not your father's Lexus. I drove the M3 sedan after the Motor Trend article rating it better overall. I think some of their points are valid but feel their overall conclusion wrong. The M3 felt a little more clumsy in tight turns and I didn't like the long throws of the manual transmission. I have no regrets.
Suspension, dual air intake, rapid fire paddle shifters when pushing the envelope.
Faux quad exhaust, dressed down interior compared to GS although glad they devoted efforts to gearing and ride.
