CarGurus Analysis: 2017 Mercedes-Benz GLS
Summary
With 656 currently listed for sale and an average price of $17,759, 34.3% of 2017 Mercedes-Benz GLS listings on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2017 Mercedes-Benz GLS 4.6 / 5 stars.
64.9% of 2017 Mercedes-Benz GLS listings on CarGurus are accident free.
Why it stands out
The 2017 Mercedes-Benz GLS stands out as a large luxury SUV that was designed to carry families in comfort without giving up Mercedes-Benz refinement. It offers three rows of seating for six or seven people and up to 94 cubic feet of cargo space, which makes it especially appealing to buyers who need real utility from a premium vehicle. Mercedes also positioned it as a full-size SUV that blends the comfort and space of the S-Class luxury sedan with some off-road capability, giving it a broader mission than a typical three-row hauler.
For 2017, the GLS was a refreshed version of the former GL, and that update brought meaningful changes. It received restyled bumpers and grilles, brighter headlights and taillights, new LED running lamps, new wheels, a nine-speed automatic transmission, a standard air suspension, and an updated dashboard, steering wheel, and infotainment system. The GLS450 came with a 3.0-liter twin-turbo V6 making 362 horsepower and 369 lb-ft of torque, while the GLS550 used a 4.7-liter twin-turbo V8 rated at 449 hp and 516 lb-ft of torque. The AMG GLS63 sat at the top with a hand-built 5.5-liter twin-turbo V8 producing 577 hp and 561 lb-ft of torque, plus a sportier chassis setup and Active Curve System for flatter cornering.
What makes the 2017 GLS especially attractive is how much equipment it offered, even in a family-focused package. Standard features included 4Matic all-wheel drive, Airmatic air suspension, heated front seats, MB-Tex upholstery, a sunroof, power-folding third-row seats, and an eight-inch touchscreen. Higher trims added features such as blind spot assist, lane keeping assist, soft-close doors, navigation, Apple CarPlay, Android Auto, and a premium surround-sound system. The main drawbacks are familiar for this class: access to the third row can be awkward, and some owners note that it does not feel as spacious as some rivals. Still, for buyers who want a luxurious seven-seat SUV with strong power and a polished ride, the 2017 Mercedes-Benz GLS has a lot to offer.

| Metric | Value |
|---|---|
| Current Average Price | $17,754 |
| Year-Round Low | $17,686 |
| Year-Round High | $19,527 |
| Average Price a Year Ago | $19,527 |

Is the 2017 Mercedes-Benz GLS a good car?
Yes — the 2017 Mercedes-Benz GLS earns a 4.6/5 user rating, which points to strong owner satisfaction. Owners consistently praise its impressive power, comfort, and engineering quality, and they also highlight its smooth, powerful performance and stylish design. For you, that makes it a strong fit if you want a large luxury SUV with three rows, real cargo utility, and a premium feel. The market also shows 34.2% of listings as good or great deals, which suggests there are worthwhile opportunities if you shop carefully.
Is the 2017 Mercedes-Benz GLS reliable?
Owners rate it 4.6/5, a strong signal of long-term satisfaction.
The owner feedback also points to a dependable-feeling ownership experience, with praise for its engineering quality and smooth performance. That said, used luxury SUVs can carry higher long-term ownership risk if maintenance history is unclear, so you should pay close attention to service records and overall condition before buying.
What should I look for when buying a used 2017 Mercedes-Benz GLS?
At 65% 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 examples from those with prior damage. Then prioritize a pre-purchase inspection, especially on suspension, electronics, and interior wear, since those areas matter a lot on a luxury SUV. Focus on overall condition and maintenance records, because a well-kept example is more likely to deliver the comfort and refinement you want.
Is now a good time to buy a used 2017 Mercedes-Benz GLS?
This looks like a moderate, selective buyer’s market, so you can shop with some leverage if you know what a good example looks like.
- Deal availability: 34.2% of listings are priced as good or great deals.
- Inventory: There are 649 listings available.
- Price trend: Prices have softened 9.08% compared with last year.
- Clean inventory: 65.0% of listings are accident-free.
If you find a listing below $17,686, that's toward the low end of the year-round range and worth acting on quickly.
What is the 2017 Mercedes-Benz GLS's resale value?
The current average of $17,754 sits slightly below last year's $19,527.
That price movement suggests the market has already adjusted downward, which can help you buy at a more favorable entry point today. For a future seller, it also means resale value may depend heavily on condition, mileage, and documentation, since buyers will likely compare your vehicle against a fairly broad used inventory. Strong maintenance records and a clean history should matter more if you want to protect value later.
Vehicles with strong owner satisfaction ratings, like this model year's 4.6/5, tend to retain buyer demand, which supports resale value over time.
Should I buy a 2017 Mercedes-Benz GLS or consider a different year?
If you're weighing the 2017 against nearby model years, here's how to think about it:
Choose the 2017 if:
- 34.2% of listings are priced as good or great deals.
- At 65% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
- Price trend: Prices have softened 9.08% compared with last year.
- Owners rate it 4.6/5 — a strong satisfaction signal.
The bottom line: The 2017 makes sense if you want a luxury three-row SUV with strong owner approval and you’re willing to shop carefully for condition and history. If you’re especially price-sensitive, you may want to compare nearby years and focus on the cleanest, best-documented example rather than chasing the lowest sticker price alone.
