I love my LS400. It's an extremely comfortable car, with a very well thought out design, both inside and out.
The interior is very spacious, and all the controls are placed in perfect positions. For example, the stereo's volume control is a very large knob that is placed in the prime position so that the driver does not even have to look down to find it. The seats are very comfortable, covered in buttery smooth leather. The rear seat has generous space, and miles of leg-room.
The Nakamichi car in the car is simply amazing. It reproduces any type of music faithfully and accurately, ranging from classical to rap. The stock 8" subwoofer plays a major role in the greatness of the system. The CD changer is located in a prime place, in a box above the spacious glove compartment.
On the outside, the car is very handsome and elegant. The stock 16" wheels are shod with V-rated tires (rated for up to 149 mph), and are quite sticky, and help the big car to handle surprisingly well. The car exhibits lots of body roll, but grip is very good for a large luxo-sedan. The trunk is huge, easily swallowing 2 very large suitcases.
The engine is a work of art in itself. The engine compartment is very clean, with black plastic covers helping to keep it looking very good. The 4.0 liter V8 engine produces a healthy 260 hp, and 270 lb-ft. of torque. This gets the big car from 0-60 mph in a good 7.1 seconds. The car can hang with other, more performance oriented cars such as a (naturally aspirated) Nissan 300Z, or a BMW 328i sedan.
