How much does the 2018 Lexus RX cost?

Prices have softened 1.03% compared to this time last year, making it a favorable time to shop this model year.

There are 1,298 listings available, which gives you a solid amount of inventory to compare.

If you find a listing below $25,644.62, that's toward the low end of the year-round range and worth acting on quickly.

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 and comfortable ride, spacious interior, and luxurious features. The RX also fits buyers who want a luxury crossover with a familiar, comfort-first character and extra passenger capacity compared with the standard setup.

That said, the added third row is a compromise, and the overview makes clear that it does not fully deliver on easy extra-passenger space. Even so, the market shows 34.2% good or great deals, which suggests there are still attractive opportunities if you shop carefully.

Is the 2018 Lexus RX reliable?

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

User feedback points to a reliable SUV with low maintenance costs, and the broader owner summary reinforces that it is a vehicle many drivers feel they can count on over time. The expert evaluation also describes the engine and transmission as smooth and responsive, which supports the impression of dependable day-to-day operation.

The ownership risk for used buyers is less about outright durability and more about whether the vehicle’s age, mileage, and maintenance history match the asking price.

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

At 61.2% 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 strong. Focus on condition details that matter most in a luxury crossover: interior wear, electronics, and evidence of prior bodywork or repair quality. Because the third row is a key part of this model year’s appeal, make sure the seating and access points work the way you expect.

Key things to evaluate:

• Trim level: The base trim includes LED headlights and fog lights, leather upholstery, keyless ignition and entry, tri-zone climate control, power front seats, an 8-inch display, and a safety suite. It also lacks Android Auto and Apple CarPlay, so you may need to budget for navigation or other tech upgrades.
• Powertrain: You get a 3.5-liter V6 with 290 hp and 263 lb-ft of torque through an 8-speed automatic. The added weight makes it a bit slower and slightly less efficient than the standard RX, at 19 mpg city, 26 highway, and 22 combined.
• 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 standard screen is 8 inches, and Android Auto and Apple CarPlay are not available. Built-in navigation and upgraded audio require extra-cost packages, and the Remote Touch interface is a drawback.
• Fuel efficiency: The RX 350L is rated at 19 mpg city, 26 highway, and 22 combined. A hybrid version is also mentioned at 31 city, 28 highway, and 30 combined, though it requires premium fuel.

Which 2018 Lexus RX trim should I buy?

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

Here's the short version:

• Base trim: This is the value starting point, but it leaves out blind-spot monitoring and modern smartphone integration. You get the core luxury and safety equipment, but not the extra convenience features many shoppers expect.
• Sweet-spot trim: The Premium Package is the best value add, bringing roof rails, a sunroof, auto-dimming side mirrors, auto wipers, driver memory, and wood trim for a relatively modest price increase.
• Premium/top trim: The Luxury trim adds 20-inch wheels, ventilated front seats, upgraded leather, wood and aluminum trim, ambient lighting, heated wood-and-leather steering wheel trim, and manual rear sunshades.
• Off-road trim: This model year does not present an off-road-focused trim for typical daily drivers.

The safety suite is a strong standard feature, but blind-spot monitoring still requires extra spending.

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

This is a moderate buyer’s market, so you can shop selectively without expecting a fire sale.

• Deal availability: 34.2% of listings are priced as good or great deals.
• Inventory: There are 1,298 listings available.
• Price trend: Prices have softened 1.03% compared with last year.
• Clean inventory: 61.2% of listings are accident-free.

If you find a listing below $25,644.62, 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 $27,049 sits slightly below last year's $27,331.

That modest decline suggests the market has softened a bit, which can help you buy more confidently now. For a future seller, it also means you should pay close attention to purchase price and condition, because both will matter when it is time to resell. A well-kept example should still hold appeal thanks to the RX’s comfort-focused reputation and broad buyer interest.

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 Top Safety Pick+ title from IIHS and a four-star overall rating from NHTSA, with four-star ratings in all tests other than side crash categories where it scored five stars across the board.

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

The standard Lexus Safety System+ includes adaptive cruise control, lane-departure warning and intervention, and forward-collision warning and intervention with auto braking. Blind-spot monitoring is not standard, so you may need to add it separately if you want broader driver-assistance coverage.

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:

• 34.2% of listings are priced as good or great deals.
• At 61.2% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Prices have softened 1.03% compared with last year.
• Owners rate it 4.64/5 — a strong satisfaction signal.
• The year’s defining twist is the added third row, even if access and packaging are compromised.

Consider the 2017 if:

• At $24,287, the 2017 costs less than the current year's $27,049 average.
• It adds meaningful equipment while keeping the RX’s comfort and premium feel.

The bottom line: If you want the extra seating experiment and are comfortable with its compromises, the 2018 is the year to target. If your priority is value, the 2017 is the smarter alternative because it costs less while preserving the RX’s core strengths.
