Faults:

The only thing that's gone wrong with this car is normal wear and tear. The brakes, tires, and a couple of fuses needed to be replaced, but I expect these issues on any car.

General Comments:

By far the best car I have ever driven and owned. I keep saying I'm going to get rid of this car and downgrade to a lower model Lexus, but I can't bring myself to sell this car. I love everything about it.

Mine has almost every bell and whistle, with the exception of heated seats. Has GPS and power everything. Driving this car long distances feels like you are sitting on your couch with a steering wheel in your hand.

The car is extremely comfortable, has great pick up for a car its size, and is deceptively quick. Also has an excellent turning radius for any car, but especially one this size. Many have been surprised to try and race me from a standing stop, and I blow right by them. The engine is very powerful yet smooth, and extremely quiet, to the point that you aren't sure if it's on or not.

Gas mileage is great on long distances. Every now and then I'll drive from Boston, MA to Montreal, Canada, and can get there easily on 3/4 of a tank (over 300 miles).

The interior is clean, with wood paneling on the center console and steering wheel. Buttons are positioned well and easy to access. I'm 6'4, and I fit comfortably in any seat, whether driving or as a passenger in the backseat.

The factory sound system is very good and crisp.

Mechanically this car is very sound. My LS has 180,000 miles on it, and still drives as though it's brand new. No issues with the engine, transmission, or anything else.

Has bright HID headlights; great for driving in darkly lit areas.

The trunk isn't very large, but is certainly very functional.

Overall, I can't say enough positive things about this car.

The only negatives I would say, is the car takes premium gas, which can be expensive, but buying this type of car, one should expect that.

The factory GPS works sporadically, however that can likely be fixed by getting an update (tough to find locally, but can find one online).

The trunk space isn't great either, as mentioned before, and as many other reviewers have said, the cup holders are very small.

Aside from that, I am totally in love with this car.

Faults:

I'm at 140,000 miles now and have put over 32,000 miles on it since I purchased it. In that time I have had to change a brake light, turn the front rotors and that's it.

Before I bought it, the timing belt, water pump, and spark plugs were changed at around 100,000 miles.

I would say nothing has gone wrong with the car, because everything done so far is just regular maintenance.

General Comments:

The car has a small but very strong engine (4.0 V8 290hp). It is very quick for its size, and I have timed a few 0-60 times in 6.2-6.4 range. It is amazing how smooth, undramatic, and effortless the motor is, even when accelerating hard. You can balance a coin on the motor and rev it without the coin falling over!

The transmission is very smooth and has 5 speeds, which really help with gas mileage. I average about 23 mpg all together.

The ride quality is great, very smooth. It is not very crisp, but is very capable of taking on corners when asked to.

I personally like the styling of the car, though many feel otherwise. Its not flashy like a BMW or 'showy' like a Mercedes. It has a more handsome understated look outside which hide its true characteristics. On the inside is where the LS400 really outshines its competitors.

The interior is very quiet at cruising speeds and at idle. So quiet I have forgotten the engine was even on a few times, it's scary quiet. The leather inside is of good quality. After 140,000 miles the driver seat has only minor wear and tear. The wood is very rich and has a quality feel as well. All of the features are still working flawlessly even after 11 years. The most amazing thing to me is how at 140,000 miles there are still NO rattles or vibrations inside. This car is superbly put together.
