The owner feedback also highlights dependable performance, sturdy construction, and a truck that feels well suited to long-term use.

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

This is a moderate market, so you can be selective without expecting a deep buyer’s market.

• Deal availability: 25.2% of listings are priced as good or great deals.
• Inventory: There are 119 listings available.
• Price trend: Prices have softened 1.32% compared with last year.

If you find a listing below $44,722 CAD, 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 $48,012 CAD sits slightly below last year's $48,656 CAD.

That small decline suggests the market has eased a bit, which can make the truck more attractive to buyers today but slightly less favourable for sellers trying to maximise return. Even so, the pricing remains relatively stable rather than sharply falling, which is a good sign for future value retention. Strong demand from shoppers who need serious towing ability can help support pricing if the truck is well maintained and properly equipped.

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:

• 25.2% of listings are priced as good or great deals.
• Price trend: Prices have softened 1.32% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.

The bottom line: If you want a heavy-duty truck with strong owner approval and a market that is not overheated, the 2018 is a sensible place to focus your search. It makes the most sense if you value the balance of capability, comfort, and current pricing. If you are especially price-sensitive, you may also want to compare nearby years to see whether a similar truck offers a better entry point.
