I'm at 68000 miles on my RX 400h and have been very happy with the car's overall drive. It has NEVER broken down or needed repairs. The interior finishes (especially the silver/aluminum finishes) scratch VERY easily, as does the exterior paint. I've replaced the tires twice - you have to get the kind that are rated for the extra weight of the car. I love the Nav system, and the one button push to close the rear door.
Nav system, automatic push button rear door, 1-touch automatic adjustment of driver's seat to individual settings (husband can quickly correct the seat to his comfort), trunk space, general ride
Give the car better gas mileage. Go back to wood details - the silver is starting to look cheap on my car. Needs tires that can hold the weight of the hybrid system. Use better quality paint!
