Used 2020 Lexus RX for Sale nearSaint Louis, MO

How much does the 2020 Lexus RX cost?

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

With 1,348 listings available, you have a solid amount of inventory to compare before you buy.

Is the 2020 Lexus RX a good car?

Yes — the 2020 Lexus RX earns 4.88/5 from owners and 8.17/10 from expert testing. The model scores 9/10 across Performance and Cost effectiveness.

You’ll see recurring praise for its luxury feel, comfort, reliability, spacious and quiet interior, and smooth ride. In practical terms, that lines up well with the RX’s role as a relaxed, upscale daily driver for you if comfort matters more than flash.

The main trade-offs are its unintuitive technology and some cabin-noise complaints at moderate speeds. Even so, the RX’s market position and feature set make it a strong fit if you want a refined midsize luxury SUV with broad appeal.

Only 36.5% of listings are priced as good or great deals, so the better examples may not sit around long.

Is the 2020 Lexus RX reliable?

Owners rate it 4.88/5, a strong signal of long-term satisfaction.

Drivers consistently describe the RX as reliable, and the ownership experience is often framed around comfort, dependability, and a trouble-free feel over time. The expert evaluation also points to Lexus’ long-running reputation for reliability and says that tradition extends to the RX.

Lexus also includes a three-year subscription to Safety Connect and a 10-year subscription to Service Connect, which adds some ownership convenience. For used buyers, the main long-term risk is less about the core mechanical package and more about making sure the specific vehicle has been maintained well and its tech features still work properly.

What should I look for when buying a used 2020 Lexus RX?

At 67.9% 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 you’re considering a higher-mileage or lower-priced example. Focus on overall condition, signs of prior bodywork, and whether the technology and driver-assistance features operate as expected.

Key things to evaluate:

• Trim level: The RX gets a refreshed look for 2020, with standard 18-inch wheels, slimmer headlights, and L-shaped taillights. The cabin is well-appointed, but the center stack looks dated, and the F Sport appearance package adds a more aggressive look along with unique interior and exterior touches.
• Powertrain: The RX 350 uses a 3.5-liter V6 with an eight-speed automatic, while hybrid versions pair that V6 with electric motors. The standard setup is smooth, and the hybrid models bring stronger fuel economy.
• Safety package: Lexus Safety System+ 2.0 is standard and includes adaptive cruise control, automatic high beams, daytime bicyclist detection, low-light pedestrian detection, road-sign assist, and lane-tracing assist. Blind-spot monitoring is available.
• Infotainment: The RX uses an 8.0-inch standard display, with an available 12.3-inch touchscreen. Apple CarPlay is standard, and Android Auto is included as well. The system is still known for being difficult to navigate, even with the touchscreen.
• Fuel efficiency: The RX 350 achieves 23 mpg combined, the RX 350L and RX 350 AWD get 22 mpg combined, and the RX 350L AWD gets 21 mpg combined. The RX 450h AWD gets 30 mpg combined, and the RX 450hL gets 29 mpg combined.

Which 2020 Lexus RX trim should I buy?

The 2020 Lexus RX is offered in 4 trim levels: RX 350, RX 350L, RX 450h, RX 450hL.

Here's the short version:

• RX 350: This is the core choice if you want the standard two-row RX with the smooth V6, strong comfort, and the best balance of price and everyday usability.
• RX 350L: Choose this if you need the added practicality of the three-row layout and can accept the higher price and slightly lower output.
• RX 450h: This is the best-value pick if fuel economy matters most, since it delivers the strongest efficiency in the lineup while keeping the RX’s comfort-first character.
• RX 450hL: Pick this only if you want the hybrid powertrain and the extra space of the longer three-row body.

Lexus Safety System+ 2.0 is standard across the lineup, while blind-spot monitoring remains available.

Is now a good time to buy a used 2020 Lexus RX?

This looks like a moderate, selective buyer’s market, so you can shop patiently but should move quickly on the right listing.

• Deal availability: 36.5% of listings are priced as good or great deals.
• Inventory: There are 1,348 listings available.
• Price trend: Prices have held steady compared with last year.
• Clean inventory: 67.9% of listings are accident-free.

If you find a listing below $32,459, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2020 Lexus RX's resale value?

The current average of $33,282 sits slightly below last year's $33,493.

That small decline suggests the RX is holding value fairly steadily rather than swinging sharply in either direction. For you as a future seller, that kind of price behavior usually points to a market that remains comfortable with the model’s reputation and feature mix.

Because the RX also has strong owner satisfaction, demand tends to stay healthy among used shoppers. That helps support resale value over time, especially if your vehicle is clean, well maintained, and accident-free.

Vehicles with strong owner satisfaction ratings, like this model year's 4.88/5, tend to retain buyer demand, which supports resale value over time.

Is the 2020 Lexus RX safe?

The 2020 Lexus RX earns good safety ratings from both IIHS and NHTSA.

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

Lexus Safety System+ 2.0 is standard, and it includes adaptive cruise control, automatic high beams, daytime bicyclist detection, low-light pedestrian detection, road-sign assist, and lane-tracing assist. A rearview camera is standard, and blind-spot monitoring is available.

One caveat is that Lexus Enform Safety Connect did not always connect reliably during testing, so you should verify that the connected-services features work properly on any used example you’re considering.

Should I buy a 2020 Lexus RX or consider a different year?

If you're weighing the 2020 against nearby model years, here's how to think about it:

Choose the 2020 if:

• 36.5% of listings are priced as good or great deals.
• At 67.9% 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 4.88/5 — a strong satisfaction signal.
• The 2020 brings a refreshed exterior, standard Apple CarPlay, and expanded standard safety tech.

Consider the 2021 if:

• At $35,559, the 2021 costs more than the current year's $33,282 average.
• It adds a few tech upgrades and new standard safety systems.

The bottom line: If you want the better value, the 2020 is the smarter starting point because it combines stable pricing, strong owner satisfaction, and a refreshed feature set. If you’re willing to spend more for a newer model with incremental upgrades, the 2021 is the cleaner alternative; otherwise, the 2020 gives you the stronger price-to-feature balance.
