The GLC300 is a beautiful SUV inside and out. The interior is simple gorgeous with quality materials. I've shuttled 5 adults in the car comfortably with a smaller adult in the center back. Living in Colorado, the GLC has been up in the mountains numerous time including snowy roads over 12,000 ft elevation through the route 70 Eisenhower tunnel. Performance from the paired 9-speed trans with the turbo 2.0 engine is outstanding. Based the E-Class chassis, it is described as the most affordable E-Class you can buy. The GLC handles very, very well providing a civilized ride. I've had numerous sports cars including a track car and the GLC is a very satisfying car to drive through twisty mountain road or on the highway. I've been very surprised by the mileage and regularly see it over 30mpg. It is rated to be 28mpg/hwy. I simply love my time spent driving this SUV. Well done MB, it is a winner! Update: After 10 months of ownership, I absolutely love this SUV! The mileage has gone up a bit and have a pic showing at 113 miles, 39.2 mpg @ 62 mph avg.. WOW! An important note to all regarding a suspension issue that has been discussed on various message boards that is simply fixed with a software update by the dealer and tire pressure change. When driving 60-70 mph over seams or bumps in the highway, the suspension will oscillate an is felt through the steering wheel. My SUV experienced this behavior after setting tire pressures in single digit weather and with warming weather, the tire pressure increased 4-6 lbs above spec. Dropping the tire pressure to spec largely fixed this issue, but was still present under certain conditions. When the dealer applied the SW update, which controls the electronic dampening on the shocks, the issue is fully resolved. BTW - I was the first person to identify this issue to the dealer, so not widely experienced by GLC 300 owners. Good on MB to listening and developing a simple and easy fix.
I mostly love my Mercedes GLC300. It's quiet, solid, powerful and drives like a dream. You can feel the quality of this car as soon as you get inside. The interior is beautiful and the controls are all at your fingertips, this car is built for safety! I love that my car is a WI FI hotspot and that I can access all sorts of apps without getting out my phone, such as gas prices, Yelp, parking, etc. The Nav system works great. A couple of things to be aware of...premium gas only. I knew this going in, but I didn't realize how much premium costs over regular and how much the prices vary from gas station to gas station. Also, I went from a hybrid sedan to this, so MPG was also a lot different. My gas pricing app gets a workout. Also, and this actually bugs me, when I use remote start, I can't program it to remember my previous settings such as heated seats, heated steering wheel, defrost, etc. It will only remember the climate control. Come on, Mercedes, even Jeeps have this feature. Overall, though, I am very pleased with this purchase.
Over all the GLC is a terrific vehicle but it does have some flaws. In this review I'm going to focus on some of them. My GLC has the 19" wheels, when I go over a small pothole or small speed bump, the car really tosses you around. The car seems to be pushed around by the wind more than it should. The USB charging ports are in the center armrest storage compartment, there's no cutout for the cable to allow you to charge your phone while having it out. There's no real good place to keep coins. The GLK had a numeric keypad, which was helpful for phone calls. Now you have to use the navigation wheel to choose numbers. That's a P.I.A. when you call a business and have to enter numbers to get to the write extension. The backup camera has terrible, really terrible, low light resolution. Its image is very grainy, buzzy, and it seems that the frame rate is very low. My GLK's was much much better. There's a touch pad over the navigation wheel. To use the wheel you rest your hand on the pad. It's easy to accidentally change stations or selection when you move your hand. On my GLC, the sunglass storage compartment sticks when I open it, plus when I press it to open it, I sometimes hit one of the mBrace buttons by mistake. When I try to fill up the gas tank the gas pump keeps shutting off. I've tried about six different stations. There must be a design flaw in the inlet. Lastly, the mpg is just meh.
I recently traded in a 2011 Lexus RX 350 AWD for the Mercedes-Benz GLC 300 4matic. The other cars I considered were the current Lexus RX 350, the Volvo XC60, the BMW X3, and the Audi Q5. I loved my Lexus when it was new, but it didn't "age" well from a fit and finish standpoint. Over time, it developed rattles, squeaks, and started to feel "sloppy". I've owned a Mercedes since the early 2000s and all of them feel just as solid new as they do when they're 10 years old. I wrote off Lexus based on the experience I'd had with the 2011 RX 350 and the hideous new body style. The Volvo XC60 looked interesting, but the revamped navigation won't be out until September at the earliest. The BMW X3 and the Audi Q5 looked like contenders, the the rear passenger room, the modern interior of the GLC, and the overall fit & finish of the GLC won me over. My other car is a 2015 Mercedes C300, which I've been delighted with. The GLC is like a C-class on stilts. One notable difference between both the C and the other SUVs I considered is the rear passenger room. Mercedes did a fantastic job laying out the back seat such that 6 footers don't feel cramped. The GLC has run-flat tires, so the storage compartment where the spare tire normally would go is opened up as storage in the rear of the car underneath the floor. It's a handy compartment to have. The seats fold down with the flip of a switch from the rear of the vehicle. You can also put them down by flipping a switch on the rear driver's side or rear passenger side doors. If you're hauling somthing long and skinny, you can put just the center section down, which is very handy. In terms of ride quality, I've been extremely impressed. The ride is very smooth. While the GLC shares the same engine as the C-class sedan, it has a 9 speed transmission instead of the C's 7 speed transmission. This makes for smooth acceleration and very good gas mileage for an SUV. I'm still under 1,000 miles on it, so I haven't done any zero-to-60 sprints but it is certainly peppier than the Lexus RX it replaced. Gas mileage and ride quality are a marked improvement over the Lexus, too. I didn't want to pay up for the panorama sunroof, but the only ones available had them. Thankfully, I was able to negotiate a good price which made getting it palatable. In hindsight, I'm delighted with it. While the car does get hot when parked in the summer, Mercedes is giving out 5 years of free mbrace, which is a phone app that enables you to remotely start the vehicle, lock/unlock doors, and send navigation destinations from your phone to the car, which is very handy. As I mentioned earlier, my other car is a 2015 C-class, which has the Burmester sound system in it. Over the past couple of years, I got very spoiled with it and it turned into a "must have" for me when shopping for another Mercedes. Having compared the two vehicles playing the same songs side-by-side, the GLC's acoustics are a little better than the C. I haven't had a chance to take the GLC on snow, yet, but I've been very impressed with the C's performance in inclement weather. I suspect I'll be similarly impressed with the GLC when winter arrives.
I bought the vehicle with the top premium package and parking assist - glad I did! Lots of convenience features but most important is the overall safety of the vehicle. Sure, it is more expensive than similar sized vehicles but the fit and finish plus the engineering are well worth the extra cost.
