    2021 GLC300 4matic

    I absolutely love this compact SUV! Coming from a Subaru Outback, this is light years above and beyond for same year. A quiet cabin is my top want for buying a car. This cabin is quiet and relaxing inside. I’m tall and there is plenty of room. The seats are incredible! Can’t wait to take it on the roads in winter.

    Exceptional Comfort

    I have had this vehicle for only one month so have not developed much experience with it. I did take it on a 1400 mile trip two days after purchase. It ran well, was very comfortable to drive, made for a very easy trip, was great on gas mileage, and it is very quiet inside the cabin. Seat comfort is exceptional and this, being our first experience with heated seats and steering wheel, was most enjoyable.

    Battery dead every night on glc300

    I owned a 2021 Mercedes glc300 loaded one. I owned it for about 8 months. I had it at the dealership more than I had it. I finally got it working but I guess not they still had trouble with it. I've heard from doing research the problem is with the radio takin to much battery and the radio running after the suv is off. The problem I had was the battery kept dieing. Some people say pull the fuse at night for the radio and see if that helps. Or keep a battery tender on at night! I put a new battery in the car didn't help

    A Surprise Flop

    This is my third car in this class. Mercedes has always been my favorite car and I have always loved my cars. Unfortunately, I just traded in my 2019, which I really wanted to keep, but the dealer wanted to charge me $4000 above my buyout price, to "certify" my own car. For me, this is a scam to get you to say, no way, and they get to keep the car, certify preown it, and make tons of money off the car. Of course I told them I will not do that, and proceeded to buy a left over 2021, with 12,000 miles on it. I thought nothing of it, and was excited they had a car for me. Well I purchased it on 5/21, it was back at the dealer all of memorial day weekend, got it back that tuesday, and was back at the dealer that Friday. I have not seen it since. The trouble was with the Blind Assist, and some electrical things. They tried upgrading it, and replacing a board or something, and they are doing it again this week. They have to confer with Mercedes to see what to do. I hate to write a terrible review, but this has been my experience thus far.

    Stylish, comfortable and safe.

    I think the vehicle is gorgeous, I feel very safe inside. I was replacing a Mercedes that was totaled in an accident, leaving me unhurt. Feeling safe was important to me. Having a vehicle that protects you when you need it is important.
