How much does the 2018 Lexus RX cost?

Prices have softened 2.01% compared to this time last year, making it a favorable time to shop this model year.

There are 1,380 listings available, which gives you a solid amount of inventory to compare.

Is the 2018 Lexus RX a good car?

Yes — the 2018 Lexus RX earns a 4.64/5 user rating and a 6.5/10 expert rating. The model scores 8/10 across Performance and Safety.

Owners consistently praise the smooth, comfortable ride, the spacious interior, and the luxurious features. The overview also points to the RX’s familiar comfort and upscale character, which makes it appealing if you want a refined luxury crossover rather than a flashy one. The main caution is that some shoppers may find the technology dated.

With 37.2% of listings priced as good or great deals, you have a decent chance of finding a competitive offer.

Is the 2018 Lexus RX reliable?

Owners rate it 4.64/5, a strong signal of long-term satisfaction.

User feedback describes the RX as reliable with low maintenance costs, and that same theme shows up in the broader owner summary. The expert evaluation also notes that the engine and transmission behave smoothly and without issues, which supports the impression of dependable day-to-day use. The cost-effectiveness commentary, though, suggests the RX L’s extra seating and packaging compromises make it a less compelling long-term value than dedicated three-row rivals.

For used buyers, the main ownership risk is not outright mechanical drama so much as paying for a vehicle whose extra seating and tech limitations may not age as gracefully as its comfort.

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

At 61.1% 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 listing price looks unusually attractive. Focus on body condition, signs of prior repair, and whether the cabin and technology still feel consistent with the mileage and asking price. Because this model’s appeal is tied to comfort and upscale presentation, condition matters a lot.

Key things to evaluate:

• Trim level: Starting with the Base trim, you get leather upholstery, tri-zone climate control, an 8-inch display, and a standard safety suite, but you do not get Android Auto or Apple CarPlay. The Premium Package adds roof rails, a sunroof, auto-dimming side mirrors, auto wipers, driver memory, and wood trim, while the Luxury trim adds 20-inch wheels, upgraded seating, and more upscale interior materials.
• Powertrain: The standard setup uses a 3.5-liter V6 with 290 hp and 263 lb-ft of torque, paired with an 8-speed automatic. The hybrid version adds two electric motors for 308 hp and stronger fuel economy, though it requires premium fuel.
• Safety package: Lexus Safety System+ is standard and includes adaptive cruise control, lane-departure warning and intervention, and forward-collision warning and intervention with auto braking. Blind-spot monitoring is not standard.
• Infotainment: The cabin uses an 8-inch display, but Android Auto and Apple CarPlay are not available. Built-in navigation and upgraded audio can add cost, and the Remote Touch interface is a notable drawback.
• Fuel efficiency: The standard RX 350L is rated at 19 mpg city, 26 highway, and 22 combined. The hybrid is rated at 31 city, 28 highway, and 30 combined mpg.

Which 2018 Lexus RX trim should I buy?

The 2018 Lexus RX is offered in 3 trim levels: Base, Premium Package, and Luxury.

Here's the short version:

• Base: This is the value starting point if you want the RX’s core luxury feel without stretching the budget. You still get leather upholstery, tri-zone climate control, an 8-inch display, and the standard safety suite, but you miss out on convenience upgrades like roof rails, a sunroof, and driver memory.
• Premium Package: This is the best-value trim for most shoppers because it adds the most useful everyday upgrades without jumping as far in price as the Luxury trim. Roof rails, a sunroof, auto-dimming mirrors, auto wipers, driver memory, and wood trim make it feel more complete.
• Luxury: Choose this if you want the most upscale cabin presentation and are willing to pay for it. The 20-inch wheels, upgraded seats, ventilated front seats, ambient lighting, and richer trim materials make it the most premium-feeling version.

The standard Lexus Safety System+ is a strong plus across the lineup, but blind-spot monitoring is not standard.

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

This is a moderate market for selective buyers, so you have room to shop carefully without expecting a fire-sale environment.

• Deal availability: 37.2% of listings are priced as good or great deals.
• Inventory: There are 1,380 listings available.
• Price trend: Prices have softened 2.01% compared with last year.
• Clean inventory: 61.1% of listings are accident-free.

If you find a listing below $25,624, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2018 Lexus RX's resale value?

The current average of $26,642 sits slightly below last year's $27,188.

That softer pricing suggests the RX is not in a rising-price phase right now, which can help you as a buyer but may limit upside if you plan to resell soon. Still, the model’s pricing remains relatively stable within its year-round range, which is a sign of steady demand rather than sharp depreciation. If you buy well, you should have a reasonable path to holding value better than a less desirable luxury crossover.

Vehicles with strong owner satisfaction ratings, like this model year's 4.64/5, tend to retain buyer demand, which supports resale value over time.

Is the 2018 Lexus RX safe?

The 2018 Lexus RX earns a four-star overall rating from NHTSA, with four-star ratings in all tests other than side crash categories where it scored five-star ratings across the board. It also earns a Top Safety Pick+ rating from IIHS.

It earns an 8/10 safety score from our experts.

Lexus Safety System+ is standard and brings adaptive cruise control, lane-departure warning and intervention, and forward-collision warning and intervention with auto braking. Blind-spot monitoring is not standard, which is a notable gap for a luxury SUV in this price range. The crash-test results are strong overall, but the standard equipment mix is not as complete as it could be.

Should I buy a 2018 Lexus RX 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:

• 37.2% of listings are priced as good or great deals.
• At 61.1% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 2.01% compared with last year.
• Owners rate it 4.64/5 — a strong satisfaction signal.
• It adds three-row seating, but the extra row is tight and best suited to occasional use.

Consider the 2017 if:

• At $24,033, the 2017 costs less than the current year's $26,642 average.
• It adds value with standard Safety System + and available F Sport across the lineup.

The bottom line: If you want the newer year with the three-row layout and can live with its packaging compromises, the 2018 is the better fit. If your priority is saving money and you do not need the extra seating, the 2017 is the smarter value play.
