How much does the 2018 Lexus RX cost?

Prices have softened 1.90% compared to this time last year, making it a favorable time to shop this model year.

Is the 2018 Lexus RX a good car?

Yes — the 4.64/5 user rating points to strong owner satisfaction, and the expert rating is 6.5/10. The model scores 8/10 across Performance and Safety.

You’re looking at a crossover that owners praise for its smooth and comfortable ride, spacious interior, and luxurious features. The overview also frames it as a comfort-first luxury SUV with a defining three-row twist, so it makes the most sense if you value refinement and passenger flexibility more than cutting-edge tech. Good and great deals account for 35.5% of listings, which suggests there are still worthwhile opportunities if you shop carefully.

Is the 2018 Lexus RX reliable?

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

Owner feedback repeatedly describes it as reliable with low maintenance costs, and the expert evaluation also emphasizes that the engine is smooth, responsive, and eager. That combination points to a used SUV that should feel reassuring in everyday driving and ownership. For used buyers, the main long-term risk is less about basic dependability and more about finding one that has been maintained well and still feels current enough for your needs.

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

At 60% 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 close inspection of bodywork, interior condition, and any signs of prior repair quality. Because this model’s appeal leans heavily on comfort and luxury features, you’ll want to make sure the cabin electronics, seats, and convenience equipment all work as expected. If you’re comparing multiple listings, focus on condition and equipment balance rather than just mileage.

Key things to evaluate:

• Trim level: The Base trim includes auto LED headlights and high beams, LED fogs and running lights, leather upholstery, keyless ignition and entry, tri-zone climate control, an 8-way power driver seat, an 8-inch display, and a standard safety suite. It also lacks Android Auto and Apple CarPlay, so base-trim shoppers should pay close attention to the infotainment setup.
• Powertrain: Every version uses a 3.5-liter V6 with an 8-speed automatic transmission. The standard setup makes 290 hp and 263 lb-ft of torque, while the hybrid option adds two high-torque electric motors for 308 hp and all-wheel drive.
• Safety package: Lexus Safety System+ is standard, and it includes adaptive cruise, 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 and the Remote Touch interface, but Android Auto and Apple CarPlay are unavailable. Built-in navigation and upgraded audio require extra-cost packages.
• Fuel efficiency: The standard model is rated at 19 mpg city, 26 mpg highway, and 22 mpg combined. The hybrid is rated at 31 mpg city, 28 mpg highway, and 30 mpg combined.

Which 2018 Lexus RX trim should I buy?

The 2018 Lexus RX is offered in 2 trim levels: Base and Luxury.

Here's the short version:

• Base: This is the best-value starting point if you want the core RX experience without stretching the budget too far. You still get the luxury essentials, the standard safety suite, and the main comfort features, but you should be aware that Android Auto and Apple CarPlay are not included.
• Luxury: This trim is for you if you want the more upscale cabin treatment, including 20-inch wheels, upgraded front seats with ventilation and extra support, upgraded leather, wood and aluminum trim, ambient lighting, manual rear sunshades, and a heated wood-and-leather steering wheel.

Lexus Safety System+ is standard, but blind-spot monitoring is not.

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

This looks like a moderate, selective buyer’s market, so you can shop with some leverage if you’re patient.

• Deal availability: 35.5% of listings are priced as good or great deals.
• Inventory: There are 1,343 listings available.
• Price trend: Prices have softened 1.90% compared with last year.
• Clean inventory: 60.0% of listings are accident-free.

If you find a listing below $25,626, 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 $26,738 sits slightly below last year's $27,256.

That modest decline suggests the market has cooled a bit, which can help you as a buyer today but may temper short-term resale gains if you plan to sell soon. Even so, the RX’s strong owner satisfaction and luxury reputation help support demand. If you keep the vehicle in good condition and choose a well-equipped example, it should remain appealing to future shoppers.

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 an 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. One caveat is that blind-spot monitoring is not standard, so you may want to prioritize a listing that includes it or budget for a vehicle that has it equipped.

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:

• 35.5% of listings are priced as good or great deals.
• At 60% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 1.90% compared with last year.
• Owners rate it 4.64/5 — a strong satisfaction signal.
• The expert summary says Lexus stretched the RX to add seating, but the extra row falls short in practice.

Consider the 2017 if:

• At $24,118, the 2017 costs less than the current year's $26,738 average.
• It adds meaningful equipment while keeping the RX’s comfort and value focus.

The bottom line: If you want the newer year with a broader market of listings and a slightly softer price trend, the 2018 is the better starting point. If your priority is spending less up front, the 2017 is the smarter value play, especially if you can find one with the right equipment and a clean history.
