What should I look for when buying a used 2018 RAM 3500?

At 66.8% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report so you can separate clean trucks from those with accident records or other red flags. After that, prioritize a thorough pre-purchase inspection, especially on a heavy-duty truck that may have been used for towing or hard work. Focus on overall condition, signs of wear, and whether the truck’s equipment and body style match the kind of use you plan to give it.

Is now a good time to buy a used 2018 RAM 3500?

This is a moderate, selective buyer’s market, so you can shop patiently but should move quickly when a strong listing appears.

• Deal availability: 26.9% of listings are priced as good or great deals.
• Inventory: There are 780 listings available.
• Price trend: Prices have softened 8.31% compared with last year.
• Clean inventory: 66.8% of listings are accident-free.

If you find a listing below $35,408, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2018 RAM 3500's resale value?

The current average of $36,062 sits slightly below last year's $39,328.

That price movement suggests the market has cooled, which can make resale a little less favorable than it was a year ago. If you buy now, you may benefit from the softer pricing, but a future sale could face more competition if values continue to ease. On the other hand, strong owner satisfaction can help support demand when it’s time to sell.

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

Should I buy a 2018 RAM 3500 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:

• 26.9% of listings are priced as good or great deals.
• At 66.8% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 8.31% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.

The bottom line:

The 2018 is the better pick if you want a heavy-duty truck with strong owner approval, modernized tech, and a market that currently offers some pricing relief. If you’re especially price-sensitive, you can also use the softer market to compare carefully against nearby years and focus on the cleanest, best-maintained truck rather than chasing the lowest sticker alone.
