Used Mercedes-Benz GLS for Sale at Zeigler Ford North Riverside IL
Frequently Asked Questions about Used Mercedes-Benz GLS in North Riverside, IL
What makes the GLS different from other luxury SUVs?
The GLS is Mercedes-Benz's flagship SUV - essentially the S-Class of their SUV lineup. It offers three-row seating for seven passengers with genuine luxury in all three rows, AIRMATIC air suspension for exceptional ride quality, and powertrains ranging from turbocharged inline-six to V8 engines. The GLS competes with Range Rover and BMW X7 but brings Mercedes's legendary refinement to the segment.
Is the GLS expensive to maintain after warranty expires?
Mercedes maintenance costs run higher than domestic brands - that's the reality of luxury vehicles. However, the GLS shares components with other Mercedes models, so parts availability is good and many independent Mercedes specialists around Chicago can handle routine service for less than dealer rates. Factor in higher maintenance costs when budgeting, but proper care keeps these SUVs running well past 100,000 miles.
What's the difference between GLS 450 and GLS 580?
The GLS 450 uses a 3.0L turbocharged inline-six with mild hybrid producing 375 horsepower - more than adequate for most driving and delivers better fuel economy. The GLS 580 steps up to a 4.0L twin-turbo V8 making 483 horsepower for significantly more power and that traditional V8 character. Unless you're regularly towing or want maximum performance, the 450 provides all the capability most buyers need around North Riverside.
Does the third row actually work for adults?
The GLS offers one of the roomiest third rows in the luxury SUV segment. Adults can sit back there for reasonable distances without feeling cramped, though it's still best suited for kids or occasional adult use. The power-folding third row and second-row captain's chairs (when equipped) make access easy, and climate controls for all three rows keep everyone comfortable.
How does the GLS handle in Chicago winters?
The GLS comes standard with 4MATIC all-wheel drive and AIRMATIC air suspension that can raise ride height for snow. It handles winter weather confidently with proper tires, though the large wheels and low-profile performance tires many GLS models wear aren't ideal for deep snow. Switching to winter tires makes a significant difference for Chicago area driving conditions.

What the GLS Brings to Three-Row Luxury
Most luxury SUVs with three rows treat the third row as an afterthought - cramped, uncomfortable, basically only useful for small kids. The GLS actually designed all three rows for real use. Yeah, the third row isn't as spacious as the first two, but adults can sit back there without their knees in their chest.
Mercedes built the GLS to compete with Range Rover and the BMW X7, which means they couldn't cut corners on refinement or features. The result is an SUV that drives smaller than its size suggests, rides like a luxury sedan despite being huge, and provides tech and comfort features throughout all three rows instead of just up front.
- Seating for seven with genuinely usable third-row space - power-folding for easy access and cargo flexibility
- AIRMATIC air suspension delivers exceptional ride quality on highways while maintaining capability for rough roads
- MBUX infotainment system with dual 12.3-inch displays provides modern tech without overwhelming complexity
The GLS 450 uses a turbocharged inline-six that produces 375 horsepower and gets paired with a 48-volt mild hybrid system. That setup delivers strong acceleration (0-60 in about 5.8 seconds) while still managing decent fuel economy for a 5,400-pound SUV. The GLS 580 steps up to a twin-turbo V8 making 483 horsepower if you want maximum power.
Interior quality matches what you'd expect from Mercedes's flagship SUV. Real wood trim, Nappa leather, ambient lighting, and attention to detail that you don't find in mainstream luxury brands. Sitting in a GLS feels noticeably nicer than sitting in an Explorer or Tahoe, which is what you're paying for with the Mercedes badge.
Technology and Features Worth Having
The GLS comes loaded with technology - some useful, some you'll never touch. The MBUX system runs two 12.3-inch screens (digital gauge cluster and center touchscreen) with voice control, navigation, and smartphone integration. It's one of the better luxury infotainment systems, though it takes time to learn all the features and settings.
Driver assistance features include adaptive cruise control, lane keeping assist, blind spot monitoring, and all the safety tech you'd expect in a luxury SUV. The 360-degree camera system actually works well for parking a vehicle this large around tight spots in Oak Park or Cicero.
- MBUX infotainment with "Hey Mercedes" voice control - works surprisingly well once you learn the commands
- Burmester surround sound system (on higher trims) delivers exceptional audio quality for road trips
- Available rear entertainment system with dual screens keeps kids occupied on longer drives to Wisconsin or Michigan
The air suspension does more than just provide a smooth ride. It can raise the vehicle for extra ground clearance when navigating snow or lower it for easier entry/exit. The system automatically adjusts damping based on road conditions and driving style, which is why the GLS handles so well despite its size.
Heated and ventilated seats come standard in front, with heating available for second and third rows. Massaging front seats are available and actually work well for longer highway drives. These comfort features matter more than they sound when you're doing the Chicago to Milwaukee run regularly with a full vehicle.
What to Know About Buying a Used GLS
Used luxury SUVs depreciate hard, which creates opportunity for buyers who want Mercedes quality without new Mercedes pricing. A three or four-year-old GLS 450 that cost $85,000 new might sell for $55,000 used - you're getting the same vehicle for $30,000 less just because someone else absorbed the depreciation.
The catch is maintenance and potential repairs run higher than mainstream brands. A set of tires for the GLS on 22-inch wheels costs more than tires for an Explorer. Brake jobs are pricier. Service intervals might require synthetic oil and Mercedes-specific fluids. These costs add up over ownership.
- Air suspension is sophisticated but can be expensive to repair if components fail - budget for this possibility on higher-mileage examples
- Electronics are complex and issues can be costly to diagnose and fix - get a pre-purchase inspection from a Mercedes specialist
- Maintenance records matter significantly - a well-maintained GLS runs reliably, a neglected one becomes a money pit quickly
When you're looking at used GLS SUVs, focus on service history first. Has it been maintained at Mercedes dealers or qualified independent shops? Are there records for oil changes, brake service, tire rotations? A complete history gives confidence the vehicle was cared for properly.
Common issues on higher-mileage GLS models include air suspension compressor wear, electronics gremlins (window switches, infotainment glitches), and the usual wear items like brakes and tires. Our inspection process catches major issues, but you should still plan for higher maintenance costs than a domestic SUV.
Why a Ford Dealer Has Mercedes Trade-Ins
We end up with luxury trade-ins like the GLS because people upgrade to our F-150s, Explorers, and Expeditions all the time. Someone gets tired of expensive Mercedes maintenance or wants something more practical for their lifestyle. They trade in the GLS, we inspect it, and if it meets our standards we offer it for sale.
The advantage for you is our pricing tends to be more competitive than luxury-brand dealers. We're not trying to protect Mercedes values or maintain brand prestige - we're moving quality used vehicles at fair market prices. If a GLS sits on our lot too long, we adjust pricing to move it rather than holding out for inflated numbers.
- Our inspection covers mechanical systems, electronics, interior condition - same thorough process regardless of brand
- Vehicle history reports show maintenance records, accident history, previous ownership - transparency about what you're buying
- Financing works the same as any used vehicle - our team structures loans based on your credit and the vehicle's value, not the badge
We don't have Mercedes-certified techs on staff, so for warranty work or complex repairs you'd need to visit a Mercedes dealer. But for inspections, oil changes, basic service, our team can handle it. Many GLS owners around North Riverside use independent Mercedes specialists for routine maintenance to save money anyway.
If you're trading in your current vehicle, we evaluate it the same regardless of what you're buying from us. Your trade value goes toward the GLS purchase just like it would toward an F-150. We're not playing games with inflated trade values to justify higher selling prices.
Making the GLS Work in Your Budget
Buying a used GLS makes financial sense if you want three-row luxury and can handle premium maintenance costs. You're getting a $90,000 SUV for $50,000-$60,000, which represents significant savings. But that savings only works if you budget for higher operating costs.
Insurance runs higher than mainstream SUVs. Premium fuel is recommended (though not strictly required). Tire replacements on 21-inch or 22-inch wheels cost $1,500-$2,000 per set. Annual maintenance might run $1,500-$2,500 depending on what needs attention. These costs are manageable but higher than owning an Explorer or Expedition.
- Used GLS pricing typically runs 35-45% below new pricing for three to four-year-old examples - significant depreciation savings
- Extended warranty options available through third-party providers can protect against expensive repairs outside original warranty coverage
- Financing rates for used luxury vehicles are competitive - our team works with lenders familiar with premium brands
The GLS makes sense for buyers who want legitimate luxury in a three-row SUV format. If you're cross-shopping with Range Rover or BMW X7, the GLS typically costs less used while offering similar features and arguably better reliability than Range Rover. Compared to Lincoln Aviator or Cadillac Escalade, the Mercedes offers more refinement and better resale value.
Resale considerations matter even when buying used. The GLS holds value reasonably well for a luxury SUV, particularly well-maintained examples with full service records. When you're ready to upgrade in a few years, a properly cared-for GLS retains more value than many competitors, which reduces total ownership costs.
Getting the Deal Done
Financing a used GLS works like any used vehicle purchase, though luxury SUVs sometimes get better rates because lenders view them as lower risk than older economy cars. Our finance team structures loans based on your credit profile, down payment, and the vehicle's value. Rates are competitive and we work with multiple lenders to find the best terms.
If you're trading in your current vehicle, we provide fair market valuations regardless of what you're buying from us. Your trade-in value applies directly toward the GLS purchase, reducing the amount you need to finance. We're straightforward about numbers - no inflating trade values to justify higher selling prices or other dealer games.
- Pre-approval available before you shop - know your budget and monthly payment range before selecting a vehicle
- Extended warranty options through reputable providers can protect against expensive luxury vehicle repairs after purchase
- Trade-ins evaluated at actual market value based on condition, mileage, and current demand for your specific vehicle
Extended warranty coverage makes more sense on luxury vehicles than mainstream brands. A transmission failure on an Explorer costs $3,000-$4,000. The same repair on a GLS might run $8,000-$10,000. For a few thousand dollars, extended coverage protects you from potentially massive repair bills that could exceed what you paid for the warranty.
Our goal is transparency throughout the process. Inspect the GLS thoroughly, take it for a proper test drive on highways and surface streets around North Riverside, verify service records exist, and understand what maintenance costs to expect. We're not hiding problems or glossing over luxury vehicle realities - we want you informed so the purchase makes sense long-term.
Come see what we have in stock currently. These luxury SUVs don't sit on our lot long when they're priced right and show well. Talk to our team about your budget, what features matter to you, and what kind of monthly payment works. We'll be straight about operating costs and help you decide if a used GLS fits your lifestyle and finances realistically.
