Great Overall Experience
Was looking to purchase a specific vehicle from this dealership. The one I wanted had a pending sale. The sale was not finalized and the salesman I was working with called me inmediately to inform me. I think everything went pretty fast once at the dealership.
GLC43AMG
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.

Great experience as soon as I walk in every one was friendly and helpful. I recommend this dealership 100%
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.

Great place
This is really a great place, they are so busy it is amazing. Pricing on some cars are fantastic. I just sent a friend there to look at one and it was gone by the time she arrived. I'm sure she'll find another. We bought an SUV, but I am also in the market for a sedan! This will for sure be my Go To place!
Great vehicle
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

Great prices good service very polite and knowledgeable staff. I bought a car from used car super store. After being tricked by lots of dealers and sales guys I was referred to them by a fiend of mine and I am glad I did go there and ended up buying a car. Very honest and straightforward sales staff.

Life Savior - A heart felt THANK YOU
Based on my experience, I have to give five stars and double it to ten. What more can I ask? Very lucky! My first call was with the service manager Alberto. He explained the details of what to do in the situation like I was experiencing and Alberto, Nick and many others worked like a great team. They are polite, kind and they followed through every promise they made, charged me the minimally necessary, and even went ABOVE and BEYOND to reduce cost knowing what I have been through. Not only the new catalytic converter was restored, but I understood my car more, oil, fluid change, the car got a new life. I knew my car was happy there. Not only I am super grateful, but I know that God will bless their service, and each one of them for their kindness! Thank you! BTW, they provided great shuttle service at no charge, my car was super clean, the 13 year old battery was replaced, I truly appreciate the attention to detail. The car was there for 9 month due to the national back order, they took SUCH GREAT CARE for the car. Here is a bit more detail: My Prius's catalytic converter was stolen 9 month ago, since then my car has been through two Toyota dealerships. I called five. I had to move my car due to the dealership change stories after got me in or asking for excessive work, some suggested welding, it became confusing and exhausting for me physically and mentally having to move the car multiple times. So I just randomly search Toyota dealership and ended up calling Toyota on Western. The call with Alberto was short and sweet, about five minutes, I decided to move my car to their location. Glad I did! Alberto was straightforward, very educational and professional. It was from him, I finally understood, why welding the catalytic for the Prius converter is wrong, and I am all for doing the best for my car. I was uplifted, and relaxed after Alberto took my car in. He also move the car from time to time to keep the break in good shape, no amount of money or compliment can be exchanged with such genuine help and willingness to do good. I am smiling, and feeling very thankful!
