Bought new in 04, hated it so traded my mom for her Audi, she's got 49K on it now and likes it. The car doesn't have the driver/road connection like my Audi or Saab and doesn't feel expensive like other Lexus cars. Around town speed is good but above 60 mph has no power. Original suspension had so-so handling & comfort. Suspension was replaced 3X by dealer bc it kept squeaking, now has K&N suspension & handles & rides better. Other then that no problems, not even brakes. Interior materials & design are cheap. MPG is pathetic. Auto trans is overeager to upshift into 2nd gear which dulls acceleration unless you stay heavy on the throttle- which eats more gas. Manual mode is worthless.
leather quality, seat comfort (other then no lumbar support), powerful Xenon lights, reliable (other then original suspension), no squeaks/rattles
Better MPG, lumbar support, cheap interior plastics, cup holders, poor sound system. Could use some added features. But new IS addresses most of these issues very well.
