What Makes a Pre-Owned 2023 Mercedes-Benz GLS Stand Out? 

The 2023 Mercedes-Benz GLS combines spacious seating, upscale materials, advanced technology, and confident performance. Its three-row design gives families and larger groups more passenger space than many luxury SUVs. The spacious cabin also provides a comfortable setting for longer drives around Peoria and beyond. 

A pre-owned 2023 GLS can be an appealing choice for drivers who want a full-size luxury SUV with premium appointments and flexible seating. Depending on the specific pre-owned GLS in inventory, available features may include advanced driver-assistance technology, premium infotainment, heated and ventilated seating, and high-end interior finishes. 

The GLS also offers a commanding driving position and substantial cargo capacity. Fold the rear seating areas as needed to make room for groceries, luggage, sports equipment, or other large items.

How Does the 2023 Mercedes-Benz GLS Compare With the 2023 BMW X5? 

The 2023 GLS and 2023 X5 approach luxury SUV design differently. The GLS emphasizes three-row versatility and generous interior space, while the X5 offers a more compact luxury SUV layout with its own performance and technology advantages. 

Rather than asking which model is better, consider which SUV better matches your needs.


The pre-owned GLS may appeal to drivers who prioritize: 

  • Three-row seating 
  • Generous passenger space 
  • A full-size luxury SUV design 
  • Flexible cargo capacity 
  • Mercedes-Benz luxury appointments 
  • A commanding view of the road 

The pre-owned BMW X5 may appeal to drivers who prefer: 

  • A two-row luxury SUV 
  • BMW design and driving characteristics 
  • A more compact overall footprint 
  • BMW technology and interior features 
  • The feel of a sport-oriented luxury SUV 

Both models can make excellent pre-owned luxury SUVs. The best choice depends on what you want from your next vehicle.

Should You Buy a Pre-Owned GLS or Pre-Owned BMW X5?  

Choosing between a pre-owned GLS and a pre-owned BMW X5 comes down to personal preference. The GLS provides three rows and the spaciousness expected from a full-size luxury SUV. The X5 offers a different approach with its two-row configuration. At Mercedes-Benz of Arrowhead, we sell pre-owned Mercedes-Benz and BMW models, giving customers an opportunity to compare both.  

Availability can also influence the decision. Pre-owned inventory changes frequently, so shoppers may find different model years, trims, mileage, colors, and features from one visit to the next.  


Where Can I Find a Pre-Owned Mercedes-Benz GLS in Peoria, AZ?  

Mercedes-Benz of Arrowhead offers a selection of pre-owned luxury vehicles for drivers in Peoria, Phoenix, and surrounding communities. Visit our dealership to explore available pre-owned Mercedes-Benz GLS models and compare them with pre-owned BMW SUVs.
