Used 2021 Mercedes-Benz GLC 300 Base for sale near Upland, CA

We recently acquired a 2025 MB 450 GLEe from Walter’s with the help of Christian Aparicio. We our longtime MB owners so it’s a high bar with us but Christian exceeded all expectations. We couldn’t be happier and will certainly contact him the next time we need a MB. Thank you Christian!

Shout out to Genesis for helping us get our dream car , she was very honest , helpful , charismatic ! Anyone will like to buy a Car from her , and she did every single think to make sure my car was clean and in good condition . Also I love my car very comfortable.

Wonderful service and staff. Angel was my point of contact. Explained everything clearly and was transparent. Helped out with all my questions and made the process smooth. Worked with Kevin in finance. Super cool dude who loves to keep it light and help his customers. Would definitely purchase another vehicle here again. Thank you!

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.

Anthony went above and beyond expectations to get the vehicle of my choice. Would highly recommend friends and family to purchase their next vehicle here.

I have the GLC43 AMG and it's awsome! It has plenty of guts and is extremely comfortable. I would highly recommend this vehicle to anyone.

I?ve been receiving emails regarding the cars, (MBZ S550 n Audi A8), that I?m currently interested in They have been updating me regarding the vehicle.

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.

This car has everything technology offers in it plus more. The feel of this vehicle is extremely smooth snd quiet. One of the best purchases of ever made. I’m extremely pleased and love it

Aaron has been very courteous and professional during my contact with the dealership. He's gone above and beyond in his approach to customer service.

Excellent experience with replacement of cracked windshield with the Brian, Service Manager and Domonique, Service Advisor at The House of Imports in Buena Park, CA

I love my new Mercedes! Ron was very helpful and friendly and helped me get my dream car. Highly recommended! Will definitely stay with the same dealership for my future purchases.

It was a kind and professional service. I went to four dealers, I chose this place. I was able to choose a good car, and I am happy and happy.

My first interaction with a representative from STG via cel phone did not result in a transaction that met my satisfaction. Some days later I was contacted by a different representative and things went very smoothly. Caesar Q and I reached an agreement that he confirmed by email. I drove down from San Jose with my trade in vehicle and a cashiers check and arrived well after dark. The truck was prepared and ready for me to perform a thorough inspection and test drive. I was inside, outside and under the truck and it was very clean and looked as good as it did in the photos. Caesar was a pleasure to meet and work with. Very friendly and easy to communicate with, he and I shared some similar interests. The paperwork went smoothly and Caesar explained everything about the process as we went along. I would not hesitate to shop at STG in the future even though it is a 7-1/2 hour drive for me. Thank you to Caesar Q and STG for making my truck buying experience a pleasurable one. Respectfully Thomas O.

Very cordial and accommodating to customers. Thank you!
