Used Mercedes GLS Mk2 Buyer’s Guide For Families 2019-Present

The Mercedes-Benz GLS Mk2, launched in 2019, redefines what a full-size luxury SUV can offer. This model stands out for its ability to blend high-end comfort, impressive performance, and practical family hauling into one massive package. Weighing over 2.7 tons yet delivering agility through advanced suspension, it’s designed for those who demand versatility without compromise.

Overview of the Second-Generation GLS

Introduced as the X167 series, the Mk2 GLS arrived in mid-2019 with a starting price around £74,000 new. It targets buyers seeking an S-Class level experience in SUV form, complete with seven seats, towing prowess up to 3,500kg, and off-road capability that’s rarely tested in real-world use. Updates in 2023 brought refreshed styling and enhanced tech, making facelifted examples even more desirable on the used market.

Available now from around £55,000 for higher-mileage AMG Line Premium trims, prices climb for low-mileage or updated models. Its sheer size—over five meters long—means it’s best for open roads rather than tight urban streets, but tech like air suspension masks its bulk effectively.

Engine Options and Performance Breakdown

The GLS lineup caters to diesel loyalists and petrol enthusiasts alike, with all models featuring 9-speed automatic transmissions and 4MATIC all-wheel drive. Here’s a quick comparison:

Diesels like the 400d offer the best efficiency for long hauls, while the AMG variant delivers supercar acceleration. All handle briskly thanks to standard air suspension with adaptive damping.

Interior Comfort and Space Excellence

Step inside, and the GLS justifies its premium tag. Even base models boast Nappa leather, heated seats front and rear, a panoramic sunroof, and Burmester audio. Seven electrically adjustable seats ensure everyone travels in luxury, with generous legroom and headroom across all rows.

• Third-Row Access: Power-folding second-row seats make entry easy for adults.
• Cargo Flexibility: 470 liters with all seats up (355 liters post-facelift), expanding to over 2,400 liters with rear rows folded.
• Tech Suite: Dual 12.3-inch screens with MBUX voice control, wireless charging, and multi-zone climate.

Owners rave about the quiet cabin and spacious third row, ideal for family road trips.

Technology and Driver Assistance Features

Mercedes packs the GLS with cutting-edge aids. Standard kit includes adaptive cruise control, lane-keeping, surround-view cameras, and blind-spot monitoring. Optional E-Active Body Control scans the road ahead to adjust suspension proactively, enhancing both comfort and handling.

Post-2023 models upgrade to improved MBUX with augmented reality navigation and over-the-air updates. Safety ratings are top-tier, with five-star Euro NCAP scores for crash protection.

Reliability Insights and Common Issues

Mercedes reliability has improved, and the GLS scores well at 4.5/5 from owners. Key watches include air suspension components (costly if failing) and electronics glitches in early units. Diesels are robust for high mileage, but V8s demand premium fuel and maintenance.

• Service Costs: Expect £500+ annually; extended warranties advised.
• Common Fixes: AdBlue system in diesels, infotainment reboots.

Check service history rigorously—full Mercedes dealer records add value.

Running Costs and Ownership Realities

Expect 25-30mpg from diesels, dropping to under 20 for petrol/AMG. Insurance groups hit 50, and road tax is steep due to weight. Tyres and brakes are pricey replacements.

Towing is a strong suit: 3,500kg braked capacity on most, with factory towbars common.

Trims, Pricing, and Market Availability

Entry AMG Line Premium offers most essentials; Night Edition or Mayfair add style. Used prices:

• 2019-2022 400d: £50,000-£65,000 (40k+ miles)
• 2023+ Facelift: £70,000-£90,000 (low miles)
• AMG 63: £90,000+

Popular for low depreciation if maintained; aim for under 50k miles.

Buying Tips for the Savvy Shopper

Inspect underbody for off-road abuse, test suspension at speed, and verify software updates. Pre-purchase inspection from a Mercedes specialist is essential. Haggle on high-mileage examples, but prioritize full history.

Alternatives like BMW X7 or Range Rover offer competition, but GLS excels in refinement.
