I really love the exterior design of this car. Probably one of the best looking cars ever. The interior is immaculate, everything flows and the touch and feel says 'solid and upscale'. The 350 is like a gazelle ready to spring. The IS-f must be a cheetah then. Immaculate build quality and leading edge technology keeps this machine running with the pack even after 3 years.
The navigation system is big, bold with beautiful colours, love the blue tooth and Mark Levinson stereo. The car is fast off the mark but well balanced. You have to love the back up camera. This is a must these days.
The sun visor should be able to extend when deployed to the side. I still have sun getting through (real pain). The IS must have a 360 all round camera. The IS must have a blind spot indicator. Safety is paramount since this vehicle has some blind spots because of the sweet design.
