This car is very nice, however, The interior is very cramped, the reason being the car was built very narrow, the same issue with the GS, although the GS has more head room than the IS. If you're driving alone the car's feel is a little better, but for the most part it's very cramped inside, the interior is built very solid, but there was rattling in the dash that was eventually fixed by the dealer. The front rims are always extremely dirty faulty break pad design? Not sure. Handling around tight corners is OK but not great.
Nice looking exterior and interior, pretty good gas mileage, AFS xenon's, cooled seats.
This car needs at least a little more power, it can be a little sluggish. Widen the car a little bit, it's much too cramped on the inside, I've been in smaller cars that felt less cramped. The air conditioner in this car is HORRIBLE, unless the ac is blowing directly on u, you'll feel minimal a/c.
