What should I look for when buying a used 2018 Lexus LS?

At 67.5% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle-history report and then prioritize a pre-purchase inspection, especially if the car has been in any prior collision. Focus on body alignment, paint consistency, wheel condition, and how the cabin electronics and suspension behave on a test drive. Because this is a luxury sedan with advanced features, you’ll want to make sure everything works as intended before you commit.

Key things to evaluate:

• Trim level: The F Sport trim adds a more aggressive look with gray 20-inch wheels, a blacked-out grille, and reshaped air intakes, while the regular LS 500 can be optioned with more exotic interior materials and finishes. The base setup is already lavish, but the higher-spec F Sport is the one that most clearly changes the car’s character.
• Powertrain: The LS 500 uses a twin-turbo 3.5-liter V6 with 416 horsepower and 442 pound-feet of torque paired with a 10-speed automatic, and it’s offered with rear- or all-wheel drive. A hybrid LS 500h is also mentioned, with two electric motors, a lithium-ion battery, and 354 combined horsepower.
• Safety package: Lexus Safety System+ is standard and includes automatic emergency braking, pedestrian detection, lane-keep assist, adaptive cruise control, and auto high beams. Blind-spot monitoring is also standard, while Lexus Safety System+ A adds active steering for semi-autonomous highway control, front cross-traffic alert, and road-sign detection.
• Infotainment: The tech suite includes an onboard owner’s manual with videos, 360-degree cameras that can pan around the vehicle, custom route programming, and an optional 24-inch head-up display. The system is feature-rich, but the interface can feel unintuitive.
• Fuel efficiency: The rear-wheel-drive LS 500 is rated at 19 mpg city and 30 mpg highway, while the all-wheel-drive version is rated at 18/27. The hybrid is rated at 25/33 in rear-wheel-drive form and 23/31 with all-wheel drive.

Which 2018 Lexus LS trim should I buy?

The 2018 Lexus LS is offered in 2 trim levels: LS 500 and LS 500 F Sport.

Here's the short version:

• LS 500: This is the trim to target if you want the core LS experience with the broadest flexibility. It gives you the twin-turbo V6, 10-speed automatic, and the option to add more exotic luxury touches, making it the best-value choice for most shoppers.
• LS 500 F Sport: This is the pick if you care more about sharper handling and a more aggressive look. It adds the sportier exterior treatment and, with the optional F Sport Performance Package, rear-axle steering, active stabilizer bars, staggered summer tires, and variable-ratio steering.

Lexus Safety System+ comes standard, while the more advanced Lexus Safety System+ A requires an extra-cost package.

Is now a good time to buy a used 2018 Lexus LS?

This looks like a moderate, selective buyer’s market, so you can shop carefully without expecting every listing to be a bargain.

• Deal availability: 35.4% of listings are priced as good or great deals.
• Inventory: There are 206 listings available.
• Price trend: Prices have softened 1.97% compared with last year.
• Clean inventory: 67.5% of listings are accident-free.

If you find a listing below $37,408, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2018 Lexus LS's resale value?

The current average of $38,825 sits slightly below last year's $39,605.

That decline suggests the market has eased a bit, which can help you as a buyer today but may temper short-term resale gains if you plan to sell soon. The current pricing also sits within a fairly tight annual range, which points to a relatively stable market rather than a dramatic swing.

If you buy well and keep the car in strong condition, you should have a better chance of preserving value when it’s time to move on. Vehicles with strong owner satisfaction ratings, like this model year's 4.75/5, tend to retain buyer demand, which supports resale value over time.

Is the 2018 Lexus LS safe?

The 2018 Lexus LS has not been tested by the Insurance Institute for Highway Safety nor the National Highway Traffic Safety Administration.

It earns a 9/10 safety score from our experts.

Lexus Safety System+ comes standard with automatic emergency braking, pedestrian detection, lane-keep assist, adaptive cruise control, and auto high beams. Blind-spot monitoring is also standard, and Lexus includes rear-side thorax airbags as standard equipment as well. If you want active steering for semi-autonomous highway control, front cross-traffic alert, and road-sign detection, you’ll need the Lexus Safety System+ A package.

Should I buy a 2018 Lexus LS or consider a different year?

If you're weighing the 2018 against nearby model years, here's how to think about it:

Choose the 2018 if:

• 35.4% of listings are priced as good or great deals.
• At 67.5% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 1.97% compared with last year.
• Owners rate it 4.75/5 — a strong satisfaction signal.
• The 2018 LS delivers a quiet cabin, premium materials, and great handling in a distinctive flagship sedan package.

The bottom line: If you want the newer fifth-generation LS with strong luxury, performance, and value, the 2018 is the better path. If you’re especially price-sensitive, you can still shop carefully and look for a well-kept example near the low end of the range, but the 2018 stands out as the more compelling choice when you want the updated design and driving character.
