History of the Lexus LS 400
The Lexus LS 400 is a full size luxury sedan and serves as the flagship for the luxury line of vehicles for Toyota. This vehicle has a rich history and has seen years of growth from its initial release in the 1980s. The Lexus LS 400 started development in 1983 with a release in 1989 and cost $1 billion to create and market.
The vehicle was designed explicitly to be an export as Lexus’s other luxury lines didn’t have much international attention. It gained wide attention upon release and has currently five generations of vehicles. This line has been a trailblazer for luxury brands and the LS 400 was among the first luxury sedans to feature an automatic tilt-and-telescoping steering wheel with SRS airbag, powered/adjustable shoulder seat belts, and an electro-chromic rear-view mirror.
The fourth generation as well even debuted the first production eight-speed automatic transmission and an automatic parking system. Initially, the Lexus LS 400 had a 4.0-liter 1UZ-FE 32-valve V8 engine, capable of 190 kilowatts (250 hp) and 353 newton-metres (260 ft⋅lbf) of torque. The horsepower on the engine was an impressive 290 hp @ 6000 rpm.
The Lexus LS 400 is a great example of the evolution of a luxury brand that has years upon years of market and technological research to make one of the best luxury vehicles that compete with other brands vying for the same attention.

Just like Matt, there are many others who share stories of high mileage Lexus LS 400s such as in this video where the owner has over 200,000 miles. You can find many forums as well where users boast about the numbers they reached while giving helpful tips and tricks to others looking to reach high mileages as well.
