How much does the 2021 RAM 3500 cost?

Prices have softened 5.74% compared to this time last year, making it a favorable time to shop this model year.

There are 1,274 listings available, which gives you a meaningful amount of inventory to compare.

Is the 2021 RAM 3500 a good car?

Yes — the 4.71/5 user rating points to strong owner satisfaction. Owners consistently praise the towing capability, handling with heavy loads, and spacious cab, and they also appreciate the ride quality compared with competitors. For you, that means this truck makes the most sense if you want heavy-duty strength with a more comfortable, daily-driver-friendly feel. With 30.1% of listings marked as good or great deals, there is still room to shop selectively.

Is the 2021 RAM 3500 reliable?

Owners rate it 4.71/5, a strong signal of long-term satisfaction.

The owner feedback also emphasizes dependable towing performance, strong heavy-load handling, and a truck that feels solid in everyday use. That kind of repeat praise matters because it suggests the ownership experience is more than just impressive on paper. For used buyers, the main long-term risk is less about the truck’s core capability and more about finding one that has been maintained well and not overworked.

What should I look for when buying a used 2021 RAM 3500?

Accident-free inventory is solid at 76.1% — always verify the vehicle history report.

You should start with a history report so you can confirm accident status, title history, and prior use before you get too far into the process. After that, prioritize a thorough inspection of the truck’s condition, especially if it has been used for towing or heavy-duty work. You should also focus on overall wear and tear inside the cab and around the bed, since those clues can tell you a lot about how hard the truck has been used.

Is now a good time to buy a used 2021 RAM 3500?

This looks like a moderate market, so you can shop selectively and still find opportunities if you move carefully.

• Deal availability: 30.1% of listings are priced as good or great deals.
• Inventory: There are 1,274 listings available.
• Price trend: Prices have softened 5.74% compared with last year.
• Clean inventory: 76.1% of listings are accident-free.

If you find a listing below $47,274, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 RAM 3500's resale value?

The current average of $47,274 sits slightly below last year's $50,153.

That price movement suggests the market has cooled a bit, which can help you as a buyer today but may also mean future resale gains are more limited if the trend continues. If you plan to sell later, the truck’s value will likely depend heavily on condition, mileage, and how well it has been maintained. Strong demand for capable heavy-duty trucks can help support pricing, but the current softening shows you should not assume appreciation.

Vehicles with strong owner satisfaction ratings, like this model year's 4.71/5, tend to retain buyer demand, which supports resale value over time.

Should I buy a 2021 RAM 3500 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:

• 30.1% of listings are priced as good or great deals.
• Accident-free inventory is solid at 76.1% — always verify the vehicle history report.
• Price trend: Prices have softened 5.74% compared with last year.
• Owners rate it 4.71/5 — a strong satisfaction signal.

The bottom line:

The 2021 is a strong choice if you want heavy-duty capability with a more upscale cabin and you value a truck that owners consistently rate highly. If your priority is getting the best possible price, you may want to compare nearby years and focus on whichever one gives you the cleanest history and strongest deal. For most shoppers, the 2021 makes sense as the primary target, while price-sensitive buyers should widen the search to nearby model years and buy the best-maintained example they can find.
