Love it!!! My salesman Ali Abdullah at Infiniti in Clarendon Hills. He was very patient, helpful, understanding with our needs. He made this experience exciting and comforting! Please ask for him, he will take care of you. Joe is amazing as well!

Best experience in sales service and deal. Mouris you are number one! Greatly appreciated! Best in performance, price, and prestige! Met my needs and expectations!

Love this place , love the service, love how fast my process was to get into my M4 .best dealer I’ve ever made business, super polite , humble and very respectful, they even car washed the vehicle, man come one I was like whatttt!!! Super happy I drove out from Hollywood and I was not disappointed. Check it out for yourself!!!!!!

I love the interior very comfortable seats very stylish exterior ,ride is good. My complain are those 19 inch Run flat tires are very loud . I will be replacing it with a regular tires probably a Perelli or Michellin tires. Brakes were service because it makes a tapping noise because it needs lubrication after 38000 miles .Over all This car is reliable . Just do regular maintainance and everything will be fine.

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!

Thank you David R, and Rene for your help getting my first car! Amazing experience!

Amazing service! Caring and attentive to my auto requests. Chris was a tremendous help. He was so patient and kind. Go get a car from STG! I have nothing but good things to say about my experience

I have a 2017 Qx50! This car is sporty and comfortable. Had to replace the radiator at 97,000 miles. Other than that it is very reliable.

Great personality and very helpful one of their car sales agent by the name of Nicholas from CMD montclair branch assisted me all through the night until closing time in obtaining my Mercedes Benz GLC 300, he just showed his dedication and compassion for the customer happiness,,,much appreciated,,,thanks again👏👏👏👍

This SUV met all my needs regarding styling, safety and pricing. I did a lot of research on Infiniti because I have a Nissan Pathfinder as well. The buying process was the easiest I’ve ever done.

Was the most amazing experience. Frank and Jerry treated as if we were royalty. Amazing

I keep returning and keep buying Infiniti because of the quality in their cars. I don’t worry about any kind of auto problems, I only drive.

I bought a car yesterday from Topline Automotive and I am very happy with it! My experience with Topline and their staff has been top notch from the beginning. I had been looking to buy a used BMW for 5 years now, and due to unforeseen circumstances I was looking to buy one within the month. I did my research and did my numbers, and found 3 really good deals. I checked out the other cars and dealers in Orange County and had my friend also run numbers on her end. I expressed interest in the car I found at Topline and called to see when I could check it out. The manager/director, Ethan Lam, helped me from start to finish. He was great! Not pushy or aggressive, very communicative, and super helpful. I filled out the online application they have on their website for financing and he found me such an awesome deal/rate, it was unbelievable. He went above and beyond and I am very happy with his efforts! The quality of the cars that Topline has is impressive. The car I ended up buying looked really clean and well-maintained. There are extensive photos for every one of their vehicles available online, so there were no surprises. They have an extremely nice selection of used luxury cars that have been well-maintained and look brand new. The car I chose runs beautifully and was such a good deal, it still feels unreal! I love my car!!! Thank you so much Ethan! I appreciate the awesome service and quality vehicle. Grateful!!!

Love this car! It’s gotten me everywhere I needed to be reliably and with no issues. It’s comfortable, luxurious, efficient yet powerful without being overly ostentatious. I especially like the 3.7 Liter v6 engine which is the same engine as in the Nissan 370X. It’s peppery with325 horsepower and rear wheel biased until the car senses a need for additional front wheel drive . I never get stuck.

Tom & Jerry in real life way better than the cartoon. Got me exactly what I wanted in a reasonable amount of time.

I love my QX50. Other than a few electrical issues, it has been a great car. It gets great gas mileage, and is a comfortable smooth ride.

Do yourself a favor and go See Jackie, she was excellent!!! I'm not a fan of car shopping usually it ends up being a pressure sale, with Jackie it was more like shopping with a friend. she worked within my budget and went above and beyond right down to finding me the exact interior and exterior color.

I worked with Mike Velasco and tj boldt. They were great at explaining the whole picture and not leaving any questions. I feel I got an honest deal with a great customer service.

I went to one of there other locations and after 7 hours they couldn't get it done, Frank was cold calling next day and 2 hours after we spoke on the phone I was signing paper work for a car 8600 more and was approved no issues

Randy at STG auto was amazing and professional. He was able to work with me to get the rate I want and super satisfied. Highly recommended!

I bought the now six year old 2017 QX50 with 47k miles on it. ( I paid 15k USD). Aside from having to replace the radiator, ( I knew it going in) it's an awesome car! It drives and handles like a sports car. It definitely doesn't sip gas, but you have to let the big dog eat! The interior is on point with a luxury feel, but if you're thing is an awesome infotainment system , this isn't the car for you. This car is all about the driving experience. The engine has plenty of power and the transmission shifts nicely. It's not the quietest cabin when driving, but that's why it has a decent sound system. This car is made for those who want a sports car drive, without the sports car price! ( This has the same engine and setup as the 370Z). For me, this car checks all the boxes for performance and drivability. I love driving this car and would recommend it.

They really try to make everything work for us and even if I was tired they try to take care out us

got a corolla here clean car good price no hassle i was with my kids they were curious to them and toys for them to play with

awesome i love the car is sporty and handle great. the comfort is excellent i would recommend this car everyone. The car has an aggressive look that would my car lover fall in love.

These guys were great to work with. Shout out to Andrew, Eddie and Harold for their hard work. We bought an 04 Honda Element from them a few weeks ago and I have no complaints. These guys work hard to make it as easy as possible to buy a car. They were easy to work with and no high pressure to buy. I gave them 4 stars only because I wish we could have haggled the price down a little bit, not because of customer service. Thanks again guys for all your hard work. Wayland Collins

We only got our Infinity 3 months ago, but enjoy it vey much! We will change Mud & snow tires off it soon in hopes of lowering road noise

Had a great experience buying a car here, Nelson and Chen helped me get into a new BMW and I cant thank them enough! Definitely coming back to get my next car after! Nelson even gave me a free oil change and car wash!!

The car is very reliable I have never had any problems out of it it’s very modern and easy to adjust to. The car has plenty of leg room, and back seat space. The truck is a great size. The ac works amazing, the windows are tinted. I love this car only selling it because I’m going the the military!

Dealership representative contacted me right away and when I ask for more details about the car I was interested in , they got back to me with the information I asked for right away.
