You have to be able to afford this much fun. Acceleration and braking are impressive. You also get all the interior space you should need. Gas mileage in city is around 11 to 15 mpg and on highway 16 to 19 mpg depending on traffic and weather conditions. Not too terrible for 577 hp. I have no complaints. Now have 41,000 miles. Replaced brake pads and rotors front and back. Not surprising . Replaced after market tires after 28,000 miles. No other issues or complaints.

Great ride, but tech lacking for the price point

After one year, my review below still applies, and based upon the loaner I received, it equally applies to the 2019 GLS450 as well as my 2018 ride. Overall the GLS450 is the best riding large SUV out there, looks great inside and out. While on paper the horsepower is the same, the V6 does not seem as gutsy as the V8 in the 2013 GL, but it is much quieter when the 9 speed is keeping RMPs down. MPG basically the same as the old V8, which is surprising. For the size of the vehicle, the glove box and center consul are surprisingly small. The new display screen is nice, much larger than the 2013, but why not make it touch screen. The 360 degree cameras are very nice, with the larger display they make maneuvering a breeze. The crazy touch pad over the control knob is clunky at best, and really a waste of effort by their engineers, just use the knob (or, make the screen a touch screen). This thing gets so hot it will burn your hand (when it was 90F the pad was 178F!). Apparently MB engineers do not realise metal to skin conducts pretty fast After two long road trips, a touch screen is must, if KIA has them MB should be embarrassed they do not. The command touch pad is like looking for a lost cursor at 80 MPH. Hoping the 2018 is as reliable as the 2013 GL which went 100K+ with only minor issues. (The car did eat tires, but it could be as much the driver as the wheel and tire package : ) ) After 6 months of ownership, the lack of technology is maddening. USB ports in the console is stupid, the touch pad is an absolute waste of effort make the console bigger and scrap that junk, the auto off is a lot of expense for nothing. I must say if they do not fix this before my next purchase I would most likely not get another MB no matter how solid the ride is. Which I must say is still great.

I absolutely love my GL450. It is the most comfortable vehicle I have driven under a $100,00 price tag. I have had it for 3 years and love it just as much today as the day I drove it off the lot. A few things I would point out. Its very very quite in the cabin. The stereo system is a pleasure to listen to. I like mine full blast and enjoy it. The ride quality is amazing. Very soft but has the UMMPH if you put it in sport mode. Its just a push of a button. I like my soft ride and saves on fuel as well. The climate controls are great and nothing to complain of or say much about but the GPS is a pain in the butt to add destinations and so. So we simply use phone apps for that. Reliability and maintenance. Reliability is great. Not once did it not start or had us stranded on a road. Not once. Maintenance is pricey. The dealer always has a good size bill when ever we go in for maintenance. Its not cheap but I knew that before hand and not complaining about it. My 450 has just about 35,000 miles and we will be trading it in for a 2019. Hopefully 2019 will be just as good if not better.

Drives like a quick sedan, super comfortable, great interior and exterior looks. Downside of gas mileage on the 550 and I don’t know about reliability as it’s still early days.
