Two Dynamic SUVs Side-By-Side

With so many amazing models to choose from, sometimes it can be hard to know which Mercedes-Benz is the right pick for you. Here at Mercedes-Benz of Huntington, we want to make your entire car-buying process as easy as possible. That's why we've taken two of our favorite SUVs and put them in this head-to head comparison.

The Mercedes-Benz GLS models are stunning and the best SUVs on the market. Available with a variety of engines and tech features, you really can't go wrong with any of them. But, if you're torn between the various trim levels of this class of SUVs, let us help. Here, we compare the mid-range trim Mercedes-Benz GLS 450 and the upper trim, the Mercedes-Benz GLS 550.

Both the Mercedes-Benz GLS 450 and the Mercedes-Benz GLS 550 are world-class, luxurious SUVs that offer three rows of seating and powerful engines paired with all-wheel drive and an automatic transmission. But, they veer off in different directions when it comes to engines and amenities.
