Fit and finish is what you would expect from Mercedes. The front seat comfort is a true relief for my aching back. Everything inside is focused on convenience for the driver. The track pad, mouses, and other interactive features make sure that everything is literally at your fingertips. The interior lighting is soothing as well as functional, especially when you have middle aged eyes that don’t see quite as well in the dark as they used to. The panoramic sunroof makes it feel like you can see the whole sky giving the car a very open feel in the front. Plus, the ceiling height is generous enough to easily fit my very tall sons. There really isn’t anything about this vehicle that I dislike except the standard floor mats. I’ll be ordering all weather mats. I do feel like there are some features that should be standard rather than optional for a luxury vehicle, but fortunately this one already had everything I needed. Also, the Denim Blue is a rich and velvety color. I had my mind set on black or dark grey initially, but I am glad that the blue was where I landed. It’s gorgeous!

I purchased a Certifed Pre-Owned GLB250 with approx. 30,000 miles on it, after previously owning a GLA250 model. This GLB250 currently has about 90,000 miles on it. I have owned over 100 vehicles, over my lifetime, and this vehicle is probably one of the best that I have ever driven,. At 6’3” tall, I have often found myself cramped in other vehicles, but not in this Mercedes! I do a great deal of traveling, so good overall fuel economy is a must for me. This GLB250 seats 7 people,(two small individuals in rear-most seats), and I’m averaging 30+ MPG on the highway. I think that the optional AMG sport appearance package is awesome, and truly sets this SUV apart from all of the others. I find that, even in the “comfort” mode, it is a blast to drive around! Mercedes really did do this model right!

Why it stands out
The 2021 Mercedes-Benz GLB stands out in the Mercedes-Benz luxury SUV lineup for its unusual flexibility. Its most distinctive feature is an optional third row of seating, which increases passenger capacity from five to seven. That makes it a compact luxury crossover that can serve buyers who want a more practical cabin layout than many vehicles in its class typically offer.
It also has an approachable starting price and a flexible interior layout, which add to its appeal. Beyond that, the GLB is described as an already capable and attractive crossover SUV, so its draw is not limited to packaging alone. For shoppers who want a Mercedes-Benz badge with added everyday usefulness, the 2021 GLB offers a compelling mix of versatility and premium presence.
