Let me give shout outs to Hal London, my salesman at Mercedes Benz of Doylestown, PA, part of the Faulkner Group, a close knit regional dealership carrying several manufacturers, to Kevin Rogers, the General Manager, who agreed to accept a personal check for the vehicle because I was from out of state and could not get a certified check issued on a holiday, and then surprised me with a further $1000 off the already great price, and to Edmunds for introducing me to the vehicle and the dealership. The car is great. Under 5000 miles, certified,etc. I've driven it about 200 miles, both highway and local. It reminds me of the Volvo V90s that I owned in the late 80s until 2005, after they were sold to Ford. (obviously before the auto electronic revolution) Not a babe-mobile, but strong and sturdy. A Bond girl in the Rosa Klebb mold, but much nicer. (If you get that reference, you're in my age range). I drove 135 miles each way for a test drive and a couple of hours of paperwork. I don't know if I'd do that again, but thank you, Edmonds, for saying it was under 100 miles. I was reluctant to buy online, and in fact I didn't buy until I sat in it and drove it, but I was extremely pleased with the results.

I’ve owned this vehicle for more than 2 weeks. Yes, during this pandemic, I haven’t had a chance to drive a lot. However, I feel nice every time when I’m in the cabin. The interior is just unique. It’s kind of futuristic but it has something to make it not to look too futuristic. The exterior is exactly what I was looking for. It doesn’t look flashy and too futuristic. It looks just like a car. Since, I really don’t need a big car at all. Also, I don’t drive fast. It doesn’t bother me that this GLB is considered entry level and has less engine performance than midsize SUV. It has everything I need. So you can’t rely on me, even though the car is slower than this, it still has everything that I need. That being said, I have no comments regarding engine and class. MBUX is nice. It can do a lot of things so I can focus more on the road. One downside is the doors. You do need to slam a bit and I don’t feel good when I slam the door. I don’t want people to think that I’m upset ;)

The perfect all-rounder for families. Mercedes has clearly made a mistake in setting in the appropriate pricing policy, since it had to slot it between Gla and Glc. I am a car engineer and I have to say that despite being based on a smaller platform the Glb should definitely cost at least 10 grant more than the Glc. Get one before prices skyrocket!
