I've had my IS for about 3 1/2 months and I have to tell you that I simply love this car! It is extremely fast, yet still has that luxurious lexus ride. In my opinion it is the perfect blend of performance and luxury. The car has definitely converted me to paddle shifters as I really, really like them. Shifting is super fast and allows you to keep your hands on the wheel. I got the sport suspension package on mine and I would highly recommend that you at least test drive the car w/the sport suspension as handling is far superior to that of the standard model. Also the push button start and key fob system is pure genius! I unlock, lock and start the car w/o taking anything out of my pocket.
Push button start and general key fob concept, paddle shifters, sport suspension package, excellent interior lighting, overall styling of the car. I can't stop looking at it
A second cup holder, cooling function that also cooled the back of the seat and not just the bottom.
