Your Lexus LS 400 made its debut in 1989 as the first Lexus to ever roll off an assembly line, and the LS nameplate still stands as Lexus' flagship luxury car. Most recently debuting an automatic parking system and the first production 8-speed automatic transmission, the LS that started with the 400 continues to make automotive history. To keep your original version running like new, it's essential to keep up with the necessary maintenance, such as oil changes and regularly checking and replacing your Lexus LS 400 spark plugs.
