How much does the 2018 Lexus LS cost?

Prices have held steady compared to this time last year, signaling a stable and predictable market for this model year.

There are 208 listings available, which gives you a modest amount of inventory to compare before you buy. If you find a listing below $37,424.44, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2018 Lexus LS a good car?

Yes — the 2018 Lexus LS earns a 4.75/5 user rating and an 8/10 expert rating. The model scores 9/10 across Cost effectiveness and Safety.

Drivers consistently praise the quiet cabin, premium interior materials, and great handling. The review summary also points to strong acceleration and a strong value proposition, while the overview reinforces the LS’s comfort, performance, and value focus. The main trade-offs are the potentially polarizing design and unintuitive technology.

With 31.3% of listings marked as good or great deals, you still have room to shop selectively if you want the right mix of condition, equipment, and price.

Is the 2018 Lexus LS reliable?

Owners rate it 4.75/5, a strong signal of long-term satisfaction.

The review summary points to reliability as part of the LS’s appeal, alongside its strong value and luxurious feel. The overview also frames the car around Lexus’s long-running formula of reliability and value, which supports the idea that this model is built to be dependable over time. The expert evaluation adds that Lexus’s value and customer-service reputation remain central to the LS’s appeal.

For used buyers, the main long-term ownership risk is less about the brand promise and more about finding a well-kept example with the right maintenance history and condition.

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

At 65.9% 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 driven hard or shows signs of cosmetic repair. Focus on cabin condition, ride quality, and how the technology operates in real use, since the LS’s strengths are tied closely to refinement and equipment. If you’re comparing multiple listings, pay close attention to whether the car’s features and condition match the asking price.

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 equipped with more exotic interior materials and trim. The safety package is standard, but the more advanced driver-assistance features require the Lexus Safety System+ A package.
• 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. Rear- or all-wheel drive is available, and the hybrid version uses two electric motors and a lithium-ion battery.
• Safety package: Lexus Safety System+ comes standard with automatic emergency braking, pedestrian detection, lane-keep assist, adaptive cruise control, auto high beams, and blind-spot monitoring. Lexus Safety System+ A adds active steering for semi-autonomous highway control, front cross-traffic alert, and road-sign detection.
• Infotainment: The main screen includes an onboard owner’s manual with videos, navigation with custom route programming, and 360-degree cameras that can pan around the vehicle. The tech suite also includes a 23-speaker Mark Levinson stereo and an optional 24-inch head-up display.
• Fuel efficiency: Rear-wheel-drive models are rated at 19 mpg city and 30 mpg highway, while all-wheel drive drops to 18/27. The hybrid returns 25/33 with rear-wheel drive 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, LS 500 F Sport.

Here's the short version:

• Base trim: The LS 500 gives you the core luxury experience, but the standard safety suite is the main feature set to focus on if you want the essentials without paying for the more aggressive performance-oriented setup.
• Sweet-spot trim: The LS 500 F Sport is the most compelling choice if you want the sharper handling, rear-axle steering, active stabilizer bars, staggered summer tires, and variable-ratio steering that make the car feel more athletic.
• Premium/top trim: The LS 500 F Sport also brings the most distinctive exterior treatment and the most driver-focused tuning, making it the best fit if you want the flagship sedan’s performance personality.

The standard safety package includes automatic emergency braking, pedestrian detection, lane-keep assist, adaptive cruise control, auto high beams, and blind-spot monitoring.

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 and still find worthwhile opportunities.

• Deal availability: 31.3% of listings are priced as good or great deals.
• Inventory: There are 208 listings available.
• Price trend: Prices have held steady compared with last year.
• Clean inventory: 65.9% of listings are accident-free.

If you find a listing below $37,424.44, 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 $39,304 sits slightly below last year's $39,547.

That small decline suggests the market has been relatively stable rather than sharply weakening. For a future seller, that kind of pricing pattern can be helpful because it points to predictable demand instead of a sudden drop in value. If you buy well and keep the car in strong condition, you’re more likely to preserve a healthy share of your purchase price.

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?

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, auto high beams, and blind-spot monitoring. Rear-side thorax airbags are also standard, and Lexus Safety System+ A adds active steering for semi-autonomous highway control, front cross-traffic alert, and road-sign detection. The main caveat is that this model has not been tested by either IIHS or NHTSA.

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:

• 31.3% of listings are priced as good or great deals.
• At 65.9% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have held steady compared with last year.
• Owners rate it 4.75/5 — a strong satisfaction signal.
• The 2018 LS delivers a distinctive mix of luxury, value, and performance, with a quiet cabin, premium materials, and strong handling.

The bottom line: If you want the LS’s fifth-generation redesign and a sedan that blends comfort, performance, and value, the 2018 is the right target. If you’re especially price-sensitive, focus on the listings that sit near the low end of the range and verify condition carefully before you commit.
