Have owned my LS 430 for about 6 months. This is the best car in the world. Super comfortable seats front/rear. Superb fit and finish. Quiet as a tomb. Killer Levinson stereo - best I have ever heard. Efficient motor can get almost 30 mpg on long trips. Navigation is easy, can't live without it now. Very quick off the line and can cruise over 100 mph silently. I go for rides just for fun/relaxation. Looks very classy too. Clients love it.
Quality you can feel. Beautiful interior. Seat comfort. Quiet ride. Fuel efficiency and large gas tank. Large trunk. Reliability - has never needed a repair.
None, but stock rims too boring, I upgraded for more stylist rims to fit the car. The new computer keys are a lttle expensive.
