I previously drove a Pontiac Bonneville, top of the line with lots of room. The reduced space of the IS took some getting used to; however, the quality, ride, handling, looks and gas mileage make up for the car being smaller. I chose metallic red with black interior. The wood looks great with the black! I test drove the G35, 325i and TL, and the Lexus won in almost every category: looks, handling, gas mileage, comfort, least ride noise and the list goes on. My advice is to be very careful not to scratch the hood since it's aluminum. I'm single and the reduced back seat room is no problem. My IS is always getting looks on and off the road; I highly recommend it. It's muscular & sexy!

A larger opening for the trunk, and a different material than aluminum for the hood.
