Yes the ride is firm and yes its competitors have more pedigree, but the ISF is what the old BMW M cars used to be - discreet.
This car really is a wolf in sheep's clothing.
The V8 is absolutely intoxicating, especially above 3500 rpms.
The steering is good and the brakes are fantastic.
The exhaust is louder than god and the gearbox is loads of fun when you're really hammering it.
My favorite thing about this car is that you get the ballistic performance with the Lexus reliability, couldn't ask for much more.
Steering, brakes, gearbox, noise.
It's one of the few cars I have driven that I wouldn't change the exhaust on.
If you own one or are thinking about buying one put the K&N cold air intake on it - it's like a whole new engine.
Ventilated seats, better navigation.
Why have the sport button?
Why isn't it always in sport mode?
If people wanted a soft, quiet version of this car they'd buy the IS 350 instead of the F.
