How much does the 2021 RAM 1500 cost?

Prices have softened 7.74% compared to this time last year, making it a favorable time to shop this model year.

There are 14,791 listings available, which suggests solid inventory for shoppers comparing trims and conditions.

Is the 2021 RAM 1500 a good car?

Yes — the 2021 RAM 1500 earns a 4.7/5 user rating, and our experts rate it 7.8/10 overall. The expert test drive data gives it a 7.8/10 rating, and the model scores 9/10 across Performance and Safety.

Owners consistently praise the refined driving experience, smooth ride, and high-quality interior. They also highlight the powerful engine performance and advanced technology, especially the infotainment system.

The trade-offs are the underwhelming base engine and the fact that advanced safety features are not standard. That makes it especially appealing if you want a truck that feels polished and well-equipped, but you should pay close attention to trim and options if safety tech matters to you.

The model’s 35.3% good-and-great-deal share suggests there are still worthwhile listings to find if you shop carefully.

Is the 2021 RAM 1500 reliable?

Owners rate it 4.7/5, a strong signal of long-term satisfaction.

The owner feedback points to a truck that feels refined, smooth, and dependable in everyday use, with many drivers praising the high-quality interior and strong overall driving experience. The expert test drive data also emphasizes that it delivers confident performance and handles both road and off-road driving with ease.

That said, used buyers should still focus on maintenance history and condition, especially on higher-output or heavily optioned trucks where wear and repair costs can matter more over time.

What should I look for when buying a used 2021 RAM 1500?

Accident-free inventory is solid at 75.7% — always verify the vehicle history report.

You should still run a history report on every listing and prioritize a pre-purchase inspection, especially if the truck has been used for towing or off-road driving. Pay close attention to cabin condition, electronics, and any signs of hard use, since those details can separate a clean truck from one that has been worked hard.

Key things to evaluate:

• Trim level: The lineup spans a wide range, from work-focused versions to the TRX, which adds a more aggressive off-road and performance character. Base-trim shoppers should pay attention to feature gaps, since advanced safety features are not standard.
• Powertrain: The TRX uses a 6.2-liter supercharged Hemi V8 with 702 horsepower and 650 pound-feet of torque, paired with an eight-speed automatic transmission. It is built for serious performance rather than efficiency.
• Safety package: The available Advanced Safety Group adds a 360-degree camera, adaptive cruise control with stop-and-go, lane-keep assist, automatic high beams, and pedestrian detection with emergency braking. Those features are not standard.
• Infotainment: A 12-inch touchscreen with Uconnect 4C and navigation is standard, along with wireless charging, Android Auto, Apple CarPlay, and over-the-air-friendly connected features through the system’s broader tech suite.
• Fuel efficiency: The TRX is rated at 10 mpg city, 14 mpg highway, and 12 mpg combined.

Which 2021 RAM 1500 trim should I buy?

The 2021 RAM 1500 is offered in 10 trim levels: Tradesman, TRX, and TRX Launch Edition.

Here's the short version:

• Tradesman: This is the entry point, so it makes sense if you want the lowest starting price and plan to keep things simple. It is the trim to consider if value matters most and you do not need the more specialized equipment found higher up the range.
• TRX: This is the standout choice if you want the most extreme performance and off-road capability in the lineup. It brings the supercharged V8, aggressive hardware, and the most attention-grabbing personality, but it is not the value pick.
• TRX Launch Edition: This is the collector-style version for buyers who want the TRX experience with added exclusivity. It is best suited to shoppers who care more about rarity and top-end presentation than price.

Advanced safety features are not standard, so you should check whether the truck you are considering includes the safety package you want.

Is now a good time to buy a used 2021 RAM 1500?

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

• Deal availability: 35.3% of listings are priced as good or great deals.
• Inventory: There are 14,791 listings available.
• Price trend: Prices have softened 7.74% compared with last year.
• Clean inventory: 75.7% of listings are accident-free.

If you find a listing below $29,667, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 RAM 1500's resale value?

The current average of $29,667 sits slightly below last year's $32,157.

That price movement suggests the market has cooled a bit, which can help you buy more affordably now but may also limit upside if you plan to resell soon. If you are a future seller, the key is to buy well and keep the truck in strong condition, because a softer market can make clean, well-maintained examples stand out more.

Vehicles with strong owner satisfaction ratings, like this model year's 4.7/5, tend to retain buyer demand, which supports resale value over time.

Is the 2021 RAM 1500 safe?

It earns a 9/10 safety score from our experts.

The safety content says crash-test ratings were not yet available at launch, so there is no official IIHS or NHTSA result to cite here. Even so, the truck is offered with more than 100 safety and security features, and the standard rear backup camera with dynamic guidelines gives you a useful baseline.

The available Advanced Safety Group adds a 360-degree camera, adaptive cruise control with stop-and-go, lane-keep assist, automatic high beams, and pedestrian detection with emergency braking. A digital rear-view mirror is also available through the Advanced Tech Group, along with other driver-assistance features such as blind-spot monitoring, rear cross-traffic alert, lane-departure warning, and front and rear park assistance with automatic braking.

The main caveat is that many of the most desirable safety features cost extra, so you should verify exactly which package a used truck has before you buy.

Should I buy a 2021 RAM 1500 or consider a different year?

If you're weighing the 2021 against nearby model years, here's how to think about it:

Choose the 2021 if:

• 35.3% of listings are priced as good or great deals.
• Accident-free inventory is solid at 75.7% — always verify the vehicle history report.
• Price trend: Prices have softened 7.74% compared with last year.
• Owners rate it 4.7/5 — a strong satisfaction signal.
• The 2021 stands out for the new TRX trim, which adds a performance-focused off-road edge.

Consider the 2020 if:

• At $27,072, the 2020 costs less than the current year's $29,667 average.
• It brings back the EcoDiesel across the lineup.

Consider the 2022 if:

• At $32,231, the 2022 costs more than the current year's $29,667 average.
• It adds a more polished cabin and stronger all-around appeal.

The bottom line: The 2021 is the right pick if you want the TRX’s standout performance and a strong mix of comfort, tech, and value. If price is your top priority, the 2020 is the better bargain; if you want a more refined follow-up, the 2022 is worth a look.
