Is the 2021 Nissan Sentra a good car?

Yes — the 2021 Nissan Sentra earns a 4.8/5 user rating and a 7.2/10 expert rating. The model scores 8/10 across Cost effectiveness and Safety.

What should I look for when buying a used 2021 Nissan Sentra?

At 68.6% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and confirm whether any prior damage was repaired properly. A pre-purchase inspection is worth prioritizing, especially if you’re comparing multiple listings with similar prices. Focus on overall condition, signs of prior bodywork, and whether the cabin and cargo area show the kind of wear that matches the mileage.

Key things to evaluate:

• Trim level: The S is the base model, while the SV adds some tech, rear disc brakes, and nicer interior materials. The SR has the nicest interior appointment and access to exclusive options like NissanConnect and the around-view monitor.
• Powertrain: All Sentra models use the same 2.0-liter gasoline engine with a CVT and front-wheel drive. The setup is tuned for commuting and efficiency rather than speed.
• Safety package: Nissan Safety Shield 360 is standard and includes intelligent forward collision warning, automatic emergency braking with pedestrian detection, lane departure warning, rear automatic braking, blind-spot monitoring, rear cross-traffic alert, a rear-view camera, a rear sonar system, vehicle dynamic control with traction control, intelligent engine brake, active ride control, intelligent trace control, hill-start assist, high-beam assist, and intelligent driver alertness. Base S models get standard cruise control, while SV and SR models come with intelligent cruise control. SR models can also be upgraded to include a 360-degree camera system.
• Infotainment: The S gets a 7-inch touchscreen, while SV and SR get an 8-inch touchscreen. Apple CarPlay and Android Auto are standard across the lineup, and wireless smartphone integration is not mentioned.
• Fuel efficiency: The Sentra returns 29 mpg city/39 mpg highway/33 mpg combined for S and SV models, and 28 mpg city/37 mpg highway/32 mpg combined for SR models.

Which 2021 Nissan Sentra trim should I buy?

The 2021 Nissan Sentra is offered in 3 trim levels: S, SV, SR.

Here's the short version:

• S: This is the value play if you want the lowest entry price and still want standard safety tech, Apple CarPlay, Android Auto, and the core Sentra experience. It is the best fit if you care most about keeping costs down.
• SV: This is the best-value trim for most shoppers because it adds nicer interior materials, rear disc brakes, and more tech without jumping to the top of the range.
• SR: Choose this if you want the nicest interior appointment and access to exclusive options like NissanConnect and the around-view monitor.

SV and SR models add intelligent cruise control, and SR models can also be upgraded to include a 360-degree camera system.

Is now a good time to buy a used 2021 Nissan Sentra?

This looks like a moderate, selective buyer’s market, so you can shop carefully and still find worthwhile listings.

• Inventory: There are 1,905 listings available.
• Price trend: Prices have softened 7.06% compared with last year.
• Clean inventory: 68.6% of listings are accident-free.

What is the 2021 Nissan Sentra's resale value?

The current average of $14,847 sits slightly below last year's $15,975.

That softer pricing can help you as a buyer now, but it also means a future seller may need to price competitively to stand out. The current market suggests the Sentra is holding value reasonably well for a compact sedan, especially given its strong value proposition and broad appeal.

If you keep the car in good condition and maintain it well, its combination of efficiency, safety, and owner satisfaction should help support demand later. Vehicles with strong owner satisfaction ratings, like this model year's 4.8/5, tend to retain buyer demand, which supports resale value over time.

Should I buy a 2021 Nissan Sentra or consider a different year?

Choose the 2021 if:

• 32.5% of listings are priced as good or great deals.
• At 68.6% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 7.06% compared with last year.
• Owners rate it 4.8/5 — a strong satisfaction signal.
• The 2021 Sentra combines strong safety, technology, and fuel economy with a more polished design.

Consider the 2020 if:

• At $14,349, the 2020 costs less than the current year's $14,847 average.
• It offers a more upscale feel with major style, technology, and driving-dynamics upgrades.

Consider the 2022 if:

• At $16,350, the 2022 costs more than the current year's $14,847 average.
