What to Inspect When Buying a Used 2016 GL-Class

Buying a luxury vehicle requires a thorough inspection. Here’s a checklist to guide you:

Exterior Inspection

• Body Panels: Look for dents, scratches, and misaligned panels that could indicate previous accidents. Check for rust, especially around wheel wells and rocker panels.
• Paint: Ensure consistent paint color and texture across all panels. Inconsistent finishes can point to repairs.
• Tires: Check for even wear. Uneven wear can signal alignment issues or suspension problems. Also, check the tread depth; replacement tires can be costly.
• Glass: Inspect the windshield, windows, and mirrors for chips or cracks.
• Lights: Ensure all exterior lights (headlights, taillights, turn signals, brake lights) are functioning correctly and are free from condensation or damage.
• Sunroof/Moonroof: If equipped, open and close it fully. Check for smooth operation and listen for any unusual noises. Ensure drains are clear.

Interior Inspection

• Seats: Examine all leather surfaces for rips, tears, excessive wear, or discoloration. Power seat functions (adjustment, heating, ventilation) should be tested thoroughly.
• Dashboard and Trim: Check for cracks, fading, or peeling trim pieces. Ensure all buttons and controls are present and functional.
• Infotainment System: Test the navigation, audio system, Bluetooth connectivity, and any other multimedia features. Ensure the screen operates smoothly and without dead pixels.
• Climate Control: Verify that the air conditioning and heating systems blow cold and hot air, respectively, from all vents.
• Headliner: Inspect for sagging, stains, or damage, particularly around the sunroof if applicable.
• Carpet and Floor Mats: Look for stains, dampness (indicating a leak), or excessive wear.
• Power Accessories: Test all power windows, door locks, mirrors, and the tailgate.

Under the Hood and Mechanical Inspection

Engine and Drivetrain

• Fluid Levels and Condition: Check engine oil, coolant, brake fluid, power steering fluid, and transmission fluid. Look for leaks or discoloration.
• Belts and Hoses: Inspect for cracks, fraying, or signs of wear.
• Battery: Check for corrosion around the terminals.
• Engine Performance: Start the engine and listen for any knocking, ticking, or unusual noises. It should start smoothly without hesitation.
• Transmission: During your test drive, shift through all gears. The transmission should shift smoothly without jerking, slipping, or hesitation. Pay attention to any warning lights on the dashboard.
• Brakes: Test the brakes for responsiveness and ensure they don’t pulsate or make grinding noises.
• Suspension: Drive over bumps and uneven surfaces. Listen for clunks or rattles. Check for fluid leaks from the shock absorbers or air suspension components.

Electronics and Safety Systems

• Warning Lights: Crucially, ensure no warning lights illuminate on the dashboard during startup or while driving. If any do, investigate immediately.
• Driver Assistance Systems: If equipped, a specialist may need to test these complex systems.

Test Drive Essentials

• Listen: Turn off the radio and listen for any unusual noises from the engine, transmission, suspension, or brakes.
• Feel: Notice how the car handles, accelerates, brakes, and corners. Does it feel smooth and composed?
• Braking: Test the brakes at various speeds. They should be firm and responsive.
• Alignment: Drive on a straight stretch of road. The steering wheel should be centered, and the car should track straight without pulling to one side.
• Road Test Variety: Drive on different surfaces and at various speeds, including highway speeds, to expose any potential issues.

The Importance of a Pre-Purchase Inspection (PPI)

Even with a thorough personal inspection, we highly recommend arranging a Pre-Purchase Inspection (PPI) by a qualified, independent mechanic, preferably one specializing in Mercedes-Benz vehicles. This inspection can uncover hidden issues that might not be apparent during a standard test drive. It’s a critical step in avoiding costly repairs down the line. You can find trustworthy specialists through resources like the National Institute for Automotive Service Excellence (ASE) website for certified technicians.

Common Issues and Recalls for the 2016 GL-Class

While the 2016 GL-Class is a well-built vehicle, like any car, it has some known areas to check. Researching recalls and common problems can save you headaches.

Potential Issues to Be Aware Of:

• Air Suspension Issues: These can be costly to repair if components fail. Listen for leaks or uneven ride height.
• Diesel Particulate Filter (DPF) Problems (GL350d): The DPF can become clogged if the vehicle is primarily driven on short, city trips without sufficient opportunities for regeneration (a cleaning cycle). Regular highway driving helps prevent this. Seek maintenance records for proper DPF care.
• Turbocharger Issues: While generally reliable, any turbocharger can develop problems over time. Listen for unusual noises or loss of power.
• Transmission Glitches: Occasional reports of rough shifting or hesitation can occur.
• Electronic Malfunctions: As with any modern luxury car, various electronic gremlins can pop up, from infotainment glitches to sensor issues.

Recalls

It’s vital to check for any outstanding recalls on the specific vehicle you’re considering. You can do this using the VIN (Vehicle Identification Number) on the National Highway Traffic Safety Administration (NHTSA) website: www.nhtsa.gov/recalls. For the 2016 GL-Class, recalls often involved issues such as potential airbag inflator problems, or concerns with the forward-facing camera. Ensure any recalled items have been addressed by a certified dealer.

Maintenance Records Are Key

A comprehensive service history is one of the best indicators of a well-maintained vehicle. Look for records showing:

• Regular oil changes and fluid flushes at recommended intervals.
• Timely replacement of wear items like brake pads, rotors, and filters.
• Any major repairs performed by a reputable Mercedes-Benz specialist or dealership.
• Documentation of any recall work being completed.

A lack of maintenance records is a significant red flag and should prompt you to either negotiate a lower price or walk away.

What to Expect Financially

When purchasing a used luxury SUV like the 2016 GL-Class, consider all associated costs:

• Purchase Price: This varies based on mileage, condition, trim level, and optional features. Generally, expect the GL350d to be the most affordable, with the AMG GL63 at the top end.
• Insurance: Luxury SUVs often come with higher insurance premiums due to their value and repair costs. Get quotes before buying.
• Maintenance and Repairs: Mercedes-Benz parts and labor can be expensive. Factor in potential costs for routine maintenance and unexpected repairs. Using an independent specialist can sometimes be more cost-effective than dealerships for non-warranty work.
• Fuel Costs: Depending on the engine and your driving habits, fuel can be a significant expense. The GL350d offers the best fuel economy, while the V8 models will consume more.
• Extended Warranty: Consider purchasing an extended warranty or service contract for added peace of mind, especially if the vehicle is out of its original manufacturer warranty.

The 2016 GL-Class offers a commanding and comfortable driving experience. The elevated driving position provides excellent visibility. Whether you choose the smooth diesel torque of the GL350d or the potent acceleration of the V8 models, power delivery is always seamless and refined. The standard 4MATIC all-wheel-drive system enhances stability and traction in various conditions. The optional air suspension masterfully soaks up road imperfections, making it an ideal long-distance cruiser. The AMG GL63, of course, adds a significant layer of sporty dynamics, tighter handling, and a more engaging exhaust note, without sacrificing all of its luxury comfort.

Competitors to the 2016 GL-Class

While the GL-Class is a formidable luxury SUV, it faced competition from other high-end marques. Understanding these comparisons might help solidify your choice:

• BMW X5: Often sportier driving dynamics, a modern interior but can be less focused on outright passenger space in the third row compared to the GL-Class.
• Audi Q7:
