I had a smooth and excellent experience purchasing my new
I had a smooth and excellent experience purchasing my new Mercedes. My sales agent was wonderful?never pushy, truly listened to what I wanted, and made the process stress-free from start to finish. Everything was transparent with no hidden agendas, and I felt completely comfortable and confident in my decision. I highly recommend working with her if you?re looking for a professional and enjoyable car-buying experience.

Great All Around!!!
Khan is the new manager at Infiniti of Glendale and he took care of our recent lease return and new purchase personally. It was an easy, no stress experience along with Jason, our sales guy and his assistant Alladin (AKA Allen). I was put off by the previous experience we had here in 2015 but the new team has earned my trust. They even gave us WIFI and several complimentary oil changes for the new car. Keep up the good work!
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.

Good for buying cars, not so good for maintaining.
In 2008, my folks bought a new Chrysler Pacifica Limited. The car sales man was great. He knew all about the car and showed us everything about it. The dealership it's self is beautiful and super clean. They also have AWESOME cars inside in which you can sit and mess around in. The overall rating is a 4 BECAUSE, it is so hard to get a hold of these guys to take the car in. We've called 4 or 5 times to only leave messages that have never been responded to, so we are planning on just going there whether they want us to or not!
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

AMAZING SERVICE!
AMAZING SERVICE! Dan went above and beyond to make sure we got the car that fit us the best. He didn’t mind us having as many test-drives as we needed and helped us get approved for the 2020 Audi Q5 when we decided. Not pushy, respectful and very helpful! Will come back for an upgrade!

Excellent experience buying my new car!
I have leased and financed a few cars in my life and I have to say how absolutely grateful and happy I am that I decided to go to Lexus Santa Monica to lease my new 2019 Lexus NX300H. From beginning to end it was the best experience I have ever had. I was helped by sales person Nima Behnia. He was very well informed about the vehicles I was test driving and answered all my questions, and boy did I hit him with a hundred questions. This was the quickest vehicle purchase ever. I think I was in and out within 3 hours. Finance dept was also great. took care of my contract quick and everything was straight forward. I didn't feel like there was any hidden anything. My new car was detailed, filled up with gas and off I went. I would definitely recommend them to my family and friends. Go GET a LEXUS!

Amazing service
I have purchased two cars from this dealership. I’m a woman on my own and always feared the stigma of getting ripped off, but both times went flawlessly. Most recently, Daniel helped me and it truly felt more like getting together with an old friend rather than a business deal. I also really enjoyed working with Hassan who did the some of the paperwork for me. I truly love going there for maintenance also because literally everyone there is friendly. Highly recommend using this dealership.
