The Lexus LS400 isn’t just a car; it’s a statement of timeless luxury, exceptional engineering, and unmatched reliability. Released in the late 1980s, this model marked a turning point in automotive history, proving that Japanese automakers could rival and even surpass their European counterparts. If you’re a car enthusiast or simply someone searching for a high-quality used luxury sedan, the LS400 carries an allure that few vehicles can match.

Why the LS400 is an Automotive Icon

When the Lexus LS400 made its debut in 1989, it wasn’t just another car; it was a game-changer. Designed to challenge the dominance of German luxury cars, it quickly earned its place in automotive history through a host of groundbreaking features and qualities, such as:

  • Smooth Power Delivery: Equipped with the revered 1UZ-FE V8 engine, the LS400 delivered a driving experience that was powerful yet remarkably quiet and refined. This engine is still considered one of the best from its era.

  • Unparalleled Reliability: Lexus emphasized durability, designing a car that could confidently exceed 800,000 kilometers with regular maintenance.

  • Luxury Craftsmanship: Hand-finished interiors and high-quality materials were used to set new standards for what a luxury car should feel like. Wood veneers, plush leather, and a meticulous attention to detail made it a standout.

  • Advanced Technology for Its Era: It offered innovative features like memory seats, automatic climate control, and an electrochromic rearview mirror that adjusted to light conditions. These features were cutting-edge in the late 80s and early 90s.

The culmination of these features earned the LS400 a reputation as a reliable, luxurious, and long-lasting vehicle, making it a strong contender to vehicles like the BMW 7 Series and Mercedes-Benz S-Class.

Tips for Buying a Used Lexus LS400

Even decades after its debut, the LS400 remains a sought-after car in the used luxury market. If you’re considering purchasing this model, paying careful attention to certain aspects will make all the difference. Below are some key areas to inspect.

What to Look for When Shopping

  1. Engine Health (1UZ-FE): Check for oil leaks, especially around the valve covers and oil pan. A smooth-sounding engine with a documented service history is critical, as scheduled timing belt replacements and oil changes are essential for this model.

  2. Transmission Performance: The automatic transmission should shift seamlessly without hesitation. Look for signs of overheating or unusual noises, which might indicate wear.

  3. Suspension Checks: Many LS400 models came equipped with air suspension, which can be costly to repair. Inspect for sagging corners or visible leaks in the system. If you notice any unevenness, budget for potential repairs.

  4. Electrical Systems: From power seats to the famous electrochromic mirror, ensure all electronic components are functioning correctly. Window regulators and climate controls are common points of wear in older models.

  5. Body Integrity: Keep an eye out for rust in hidden areas, alignment of body panels, and any signs of frame damage from previous accidents.

Ownership Costs to Keep in Mind

While well-kept LS400s are known for reliability, they do come with specific cost considerations:

  • Parts Availability: While many essential parts are still obtainable, some specific trim components or electronics may require sourcing through online forums or specialized dealers.

  • Specialist Mechanics: Not every local shop will have the expertise to repair an older luxury sedan. Seek out technicians knowledgeable about Lexus and Toyota models.

  • Increased Maintenance Costs: Compared to modern cars, there may be higher costs associated with repairs and regular servicing, especially for advanced systems like air suspension.

Preserving and Enjoying Your LS400

Once you own an LS400, preserving its longevity is key to enjoyment. Many enthusiasts turn these vehicles into cherished collector’s items or even reliable daily drivers. Here are some tips for long-term maintenance:

  • Stick to Service Intervals: Follow the manufacturer-recommended service guidelines, including oil changes, timing belt replacements, and brake flushes.

  • Use High-Quality Parts: Ensure that compatible, high-grade parts are used for replacements. Avoid cheap aftermarket options that could compromise performance.

  • Address Issues Promptly: Minor problems like oil leaks or failing electronics can grow into costly repairs if ignored. Frequent check-ups can save significant time and expense.

What Makes the LS400 Loved by Owners?

There’s no shortage of reasons why the Lexus LS400 remains adored by car lovers and collectors. Here are a few standout aspects that keep it relevant:

  • Comfortable Ride: The supple suspension and quiet cabin continue to provide luxury-level comfort, even by today’s standards.

  • Durability: Many LS400s are still on the road today, a testament to their superior craftsmanship and engineering.

  • Collector Appeal: As interest in classic Japanese cars grows, especially in the Gulf region, well-preserved LS400s are beginning to appreciate in value.

A: Yes, essential parts remain accessible through Lexus dealerships, online retailers, and specialized sellers. Hard-to-find components can often be sourced through automotive forums or communities.
