You should run a vehicle history report on every candidate and pay close attention to any prior collision records, title issues, or repeated repairs. A pre-purchase inspection is especially important here, since condition can vary a lot from one used example to another. Focus on signs of wear, repair quality, and how well the car’s interior and electronics have held up.

What is the 2018 Chevrolet Impala's resale value?

The current average of $12,820 sits slightly below last year's $13,263.

That softer pricing suggests the model is still accessible on the used market, but it also means future sellers may not see strong appreciation from current levels. If you buy well and keep the car in good condition, you can help protect value, but the recent trend points to a market that is more stable than rising. Strong demand for roomy, comfortable sedans can still support resale, especially if your car has clean history and solid maintenance.

Vehicles with solid owner satisfaction ratings, like this model year's 4.33/5, tend to retain buyer demand, which supports resale value over time.

Should I buy a 2018 Chevrolet Impala 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:

• 27.5% of listings are priced as good or great deals.
• At 52% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 3.34% compared with last year.
• Owners rate it 4.33/5 — a solid satisfaction signal.

The bottom line: The 2018 is a good choice if you want a roomy, comfortable full-size sedan and you can find one with clean history and strong maintenance records. If you’re especially price-sensitive, it also makes sense to compare nearby model years and focus on the best-maintained example rather than the newest badge alone. For most shoppers, the 2018 is the better path when you value comfort, space, and a favorable current price; a different year may be worth considering if you’re chasing the lowest possible purchase price.
