Wasn't the IS350 supposed to be the 3 series killer- I wonder what happened?
Last I checked, the 3 series is healthy and getting even stronger.
The IS-F will be an M3 killer as the IS350 was a 3 series killer.
Lexus can huff and puff all they want, but the fact of the matter is delivering a high performance vehicle is different from mass producing vehicles, and it is different from bolting a 5.0 litre V8 on a chasis.
It takes series of iterations to get it right, and the first iteration won't do it.
