I am extremely happy w/ my IS300 This car has the soul of a tiger. The handling is outstanding, and performance is great, but the styling is what I really love. Granted, the styling is "not your father's Lexus", but it is very nice indeed. For thousands of dollars less than its main competitors, you get alot of bang for your buck.
This, of course, is not a perfect car. The gas mileage is less than average (expect about 18-20 mpg), and the trunk space is extremely lacking.
Smooth engine, beautiful styling, awesome handling.
