I had such a great experience at Mercedes-Benz of
I had such a great experience at Mercedes-Benz of Riverside! Christian was incredibly helpful from start to finish—he really took the time to listen to what I was looking for and helped me find the exact C300 I had in mind. He was patient, knowledgeable, and made the whole process smooth and stress-free. I couldn’t be happier with my new car! I would definitely recommend Christian and this dealership to anyone in the market for a Mercedes.

George was great, professional and courteous when we visited Audi of Pasadena on Monday August 18. George showed us the cars that we were interested in and provided all the features the car was equipped with, he also allows us to test drive the car. George deserves 5 stars for his positive attitude and friendly demeanor. We salute you and thank you for going above and beyond by explaining all the features of the Audi A6 sport back e tron.

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.

I live in Las Vegas.
I live in Las Vegas. After being lowballed by multiple dealerships in Vegas, I decided to try my luck with selling my car privately. Omar from STG reached out and offered me the private party value for my vehicle, as a trade-in to STG. He said STG could pick the car up for a small fee or I could drive it down to their location in Montclair, CA. I was very hesitant on working with STG, as there are so many horror stories about crooked used car dealers. I felt I would be in a vulnerable position if I were to drive the car there and they were to lowball me. I decided the risk was worth it to me for the extra money, and I drove it down. Immediately, Danny greeted me and started the inspection process. I had been upfront and honest with them about small imperfections the vehicle had, so there were no surprises. After inspecting the car, Danny confirmed that they would purchase the vehicle from me for the previously agreed-upon price. This is a standup dealership with great customer service. I feel I was treated very fairly and I would absolutely recommend them to anyone looking to get top dollar when trading their vehicle. They even gave me a ride to the airport after the deal was completed. Thank you for making the process so easy!

Buying a Used CX9 from Cardinale Mazda of Corona
After 3 trips to the dealership we wound up buying the used 2022 CX-9 we had been looking at all along. We appreciated the courtesy, professionalism, knowledge of the product, and minimal sales pressure of Taylor, the sales rep. He went out of his way to help us before, during, and after the selling process. The only reason for our review's less than perfect 5 is that a follow up email to obtain contract information, and a postal mailing of an owner's manual were both forgotten resulting in us having to make needless 25 mile drives back to the dealership. These were promised by a finance person, not the sales person.
